Clock Drift: Over time the clock on a X26E can drift. Clock drift is a phenomenon where a specific clock runs faster or slower than a reference clock. All clocks, digital or analog, can drift for various amounts of time based on many factors including; natural component tolerances, environment temperature, power supply, age of components, etc. Periodic time synchronization is needed to keep the time accurate on the CEW. If a CEW is not connected to Evidence Sync for an extended period of time the time shown on logs can be off from what is expected due to the drift of the clock. The time drift on the X26E can be up to +/- 4 minutes per month.
Clock Reset: If a CEW is left without a battery for an extended period of time, the internal clock will reset back to its factory default January 1, 2000 at midnight (based on Greenwich Mean Time, local time may show December 31, 1999). Once power is applied to the CEW again, the clock will begin to run again, with the new reset time reference. This is similar to a microwave oven blinking “12:05” 5 minutes after power returned from an outage. The clock will need to be synchronized to reflect the accurate time again.
There is no way to retroactively update or edit the logs, however there may be methods to calculate the accurate time. If you require more information about how our CEWs log events please attend a training course (Click here for Taser Training) or if you require information involving an active investigation or clock correction calculation, please contact our Investigations Department (link to Investigations).
