*This report does not provide a warranty or guarantee concerning the compliance status of the equipment checked in the submitted tests. The code samples used as a basis for analysis are representative of the code executed by the system in normal operation, but may not encompass each and every time-related function present in the tested systems. The analysis represents an opinion based on the code samples and information collected, and is intended for use as input into a risk management process.
The testing which took place at Exbridge Branch of Sainsburys focussed on testing in-store embedded systems for millennium compliance. The target list comprised systems that make use of microprocessors, but are not classed as I.T. hardware, such as the refrigeration controllers.
A total of 18 types of systems were investigated for testing. By the end of the testing period all 18 had been tested, of which two are currently undergoing a further investigation to clarify particular compliance issues.
Overall, the findings reveal:
- Little or no risk of failure in standby generators, cash counters, bakery systems and electronic scales.
- Slight risk of failure in different types or models of label printers, refrigeration plant monitoring and leak detection systems, air handling and security systems.
All of the systems tested in this report were compliant, although in many cases that only applies to a particular version of software being run by the tested system. There are clear examples of systems of identical make and model that differ in their compliance status as a result of the version of software code they are running.
Recommendations
In light of the testing carried out at Exbridge, and findings from other testing carried out on embedded systems in retail environments, the following three points have been identified as requiring specific attention.
- The version of software an embedded system is running is critical to determining the compliance status of the system. Where vendor statements of compliance are being sought it is vital to identify which versions of software the compliance statements are applicable to.
- Not all vendor statements of compliance have been proved to be correct, so it is important to obtain an independent verification of embedded systems compliance for any business critical items. Date roll-over testing on stand-alone embedded systems is generally safe to do, and should be used in conjunction with Delta-T Probe testing where possible.
- All companies involved as product and service suppliers to Sainsburys should be advised to independently test their business-critical embedded systems to a achieve a similar level of confidence in their compliance status.

Figure System Testing Process Flowchart
The Trend 921 controller is of a very modern design, and contained a number of SMT (surface mounted chip technology) chips that could not be connected to. This prevented a Delta-T Probe test from being performed.
Two options are open for testing this controller:
- Date roll-over witness test of operator functionality
- Re-test with Delta-T Probe and surface-mount clip kit (now available as an add-on product)
Any date-testing must be performed with the controller in operational mode, with the date set in the controller via the front-end software application. The following page provides a check-list table against which date testing should be performed.

Overall Conclusion
[ ] Inconclusive based on sampled information provided
[X] No detected evidence of RTC or date in memory
[ ] No detected evidence of date comparison in any code sample
[ ] Detected evidence of date comparison, correct implementation
[ ] Detected evidence of date comparison, incorrect implementation
Analysis Report
Inspection of the circuit board showed a 32KHz clock-crystal capable of providing an accurate timing reference, but no real time clock chip. Analysis of the contents of system memory showed no date or time storage, with the only time-related activity being a counter variable. Decoding the counter showed that the system is measuring elapsed time from the start of each day.
It is therefore totally unlikely that the system can or will suffer any sort of date-related failure.

Analysis Report
Inspection of the circuit board showed no real time clock chip and no clock-crystal capable of providing an accurate timing reference. Analysis of the contents of system memory show only time-related activity being a counter variable, probably derived from counting an approximation of the processor clock frequency cycles. The code samples show the identified clock locations being written and read, but no comparisons taking place.
It is therefore totally unlikely that the system can or will suffer any sort of date-related failure.

Analysis Report
Inspection of the circuit board showed the presence of a real time clock chip and 32KHz clock-crystal capable of providing an accurate timing reference. Analysis of the contents of the system memory shows both time and date-related activity taking place.
The code sample taken from the date being read shows that no year-date comparison is taking place. The year-date is simply being read as part of a data logging process which will have no impact on the ability of the equipment to operate.

The above code sample was matched to a section of code previously validated as compliant.
It is therefore totally unlikely that the system can or will suffer any sort of date-related failure.

Analysis Report
The RMS Synchro controller is of a very modern design, and contains a number of SMT (surface mounted chip technology) chips that cannot be connected to. The RAM chip was tested using a prototype SMT clip, but the ROM was of a square SMT design with pins on all edges, which prevented a full Delta-T Probe test from being performed.
Inspection of the circuit board showed the presence of a real time clock chip and 32KHz clock-crystal capable of providing an accurate timing reference.
Analysis of the contents of the system memory showed no time and date-related activity taking place. From this we know that if the date is being used it is being read directly from the RTC chip. However, no connection to the RTC chip or the code-bearing ROM was possible, so the Delta-T Probe test is inconclusive.
The mode of operation of the equipment can be assessed to gain a level of certainty regarding compliance. Documentation and available menus in the software shows that the controller can be programmed with date and time, but cannot be programmed to schedule activity on specific dates. This renders it highly unlikely to be susceptible to a date-related problem. The date is probably only used for data logging.
To gain a higher degree of confidence date-testing must be performed with the controller in operational mode, with the date set in the controller via the front-end software application. The following page provides a check-list table against which date testing should be performed. It is suggested that these date tests are performed in conjunction with the supplier, or on an identical system at the supplier’s premises.

Inspection of the circuit board showed the presence of a real time clock chip and 32KHz clock-crystal capable of providing an accurate timing reference. Analysis of the contents of the system memory shows both time and date related activity taking place.
The code sample taken from the date being written show that the 146818 RTC chip is being read and the register contents copied directly to RAM. The system is making use of Seconds, Minutes, Hours, Days, Months and Years. The 146818 will process the date change pre-during and post-millennium correctly, so there is no risk of leap-year date non-compliance. This is shown in the code excerpt below.

The application allows for programming of timing schedules based on day-of-month, but not on month or year. This is reflected in the code captured from the date being read, which does not show any year-based comparisons.
A point of note, observed during code validation, is that the date and time in the system tested was incorrect, and had a value of:
23:59:11 29/12/01
It is totally unlikely that the system can or will suffer any sort of date-related failure.

Analysis Report
Inspection of the circuit board showed the presence of a real time clock chip and 32KHz clock-crystal capable of providing an accurate timing reference. Analysis of the contents of the system memory shows both time and date related activity taking place.
The code sample taken from the date being written show that the 146818 RTC chip is being read and the register contents copied directly to RAM. The system is making use of Seconds, Minutes, Hours, Days, Months and Years. The 146818 will process the date change pre-during and post-millennium correctly, so there is no risk of leap-year date non-compliance. This is shown in the code excerpt below.

The code captured from the date being read clearly shows the year date being read and a date window being implemented by subtracting 99+[date window offset held in Register C] from the current year. By implementing this code the manufacturer has taken pre and post-year 2000 dates into account for data logging and operational functionality. The code excerpt illustrating this comparison is shown below:
EX: 2EFC 90 13 3E MOV DPTR,#0133Eh

A point of note, observed during code validation, is that the date and time in the system tested was incorrect, and had a value of:
06:36:28 31/02/99
Although it is possible to program the real time clock with such a date (Feb 99 only has 28 days, not 31) the real time clock chip that the system uses will not reach that date by itself.
It is totally unlikely that the system can or will suffer any sort of date-related failure.

The code sample taken from the date being read is the same as the code run by the Trend IQ131 (but compiled to a different range of addresses) and shows that no year-date comparison is taking place. The year-date is simply being read as part of a data logging process which will have no impact on the ability of the equipment to operate.
Further examination of the code shows operations being timed on a day-of-week basis only.
It is therefore totally unlikely that the system can or will suffer any sort of date-related failure.

A point of note, observed during code validation, is that the date and time in the system tested was incorrect, and had a value of:
00:00:12 25/01/99
Although the system clearly maintains a clock with a date, no applications code was sampled making use of, or accessing, the information. It is therefore totally unlikely that the system can or will suffer any sort of date-related failure.

Analysis Report
Inspection of the circuit board showed the presence of a real time clock chip and 32KHz clock-crystal capable of providing an accurate timing reference. Analysis of the contents of the system memory shows both time and date related activity taking place.
The code sample taken from the date being written show that the 146818 RTC chip is being read and the register contents copied directly to RAM in the range 0122 - 0126. The RTC will process the date change pre-during and post-millennium correctly, so there is no risk of the clock interpreting leap year dates incorrectly. This does not, however, apply to any calculations based on the current clock values.
The memory locations were not correctly identified or selected for the testing, so the code captured is not relevant to date / time calculation operations.
It is suggested that further follow-up testing be carried out with the system manufacturer.
