Information

Determining the correct time a particular application event occurred on a system is critical when conducting forensic analysis and investigating system events.

The three authoritative time sources for Samsung Android 7 with Knox are an authoritative time server that 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), or the wireless carrier.
