This function returns an estimate of the server UTC time without placing a network call to the PI Server each time it is called. It returns the current UTC time plus the offset between the server time and the local system time. The function periodically updates the offset. When the current server time is needed frequently, this function should be used instead of pitm_servertimeutc. The sub-second portion is included.

The server UTC time. The sub-second portion is included.
