Discussion

Determining the correct time a particular application event occurred on a system is critical when conducting forensic analysis and investigating system events. Periodically synchronizing internal clocks with an authoritative time source is needed in order to correctly correlate the timing of events that occur across the enterprise. The two authoritative time sources for mobile operating systems are an authoritative time server which is synchronized with redundant United States Naval Observatory (USNO) time servers as designated for the appropriate DoD network (NIPRNet or SIPRNet) or the Global Positioning System (GPS). Timestamps generated by the audit system in mobile operating systems shall include both date and time. The time may be expressed in Coordinated Universal Time (UTC), a modern continuation of Greenwich Mean Time (GMT), or local time with an offset from UTC.
