${longdate:universalTime=Boolean}

• universalTime - Indicates whether to output UTC time instead of local time.Boolean Default: False

NLog uses local-time by default, but because conversion from machine-time to local-time has an overhead, then NLog uses cached time-source FastLocal with 15ms time-precision that follows Environment.TickCount. For high time-precision and still fast performance, then consider using Time-source AccurateUtc (Time-precision of 1ms)
