Back to T3.6.7 - P4 - CLOCK SYNCHRONIZATION
Where a computer or communications device has the capability to operate a real-time clock, this clock should be set to an agreed standard, e.g. Coordinated Universal Time (UTC- or local standard time. As some clocks are known to drift with time, there should be a procedure that checks for and corrects any significant variation.
The correct interpretation of the date/time format is important to ensure that the timestamp reflects the real date/time. Local specifics (e.g. daylight savings) should be taken into account.
