Time Format
The Time Format menu can set the Local Time to 12-HR or 24-HR mode. UTC time will
always be shown in 24-HR model. This page will also identify which mode is currently active.
Time Set
The Time Set menu allows the user to set UTC time or Local Time. GPS time is shown if
currently available.
The UTC time can be set to a different time than the GPS time, even when GPS time is
available. In this case, the time basis will continue to be synchronized, but the manual UTC
time will be stored and remembered as an offset to the GPS time. The SYNC UTC function
can be used to reset a manually modified UTC time back to GPS time (if GPS time is
currently available).
Seconds can only be set/reset to zero. UTC seconds cannot be set if a current GPS time is
available; it will always be synchronized with GPS seconds. Local seconds cannot be set; it
will always be synchronized with UTC seconds.
