This is useful when the client wants to specify the UTC time and the wall-clock offset explicitly
rather than using time zones. This function should be used instead of User::SetUTCOffset() and
User::SetUTCTimeAndOffset().
If this function has been called the time zone server will use the value returned by User::UTCOffset()
as the offset value when doing time conversions. Calling User::SetUTCOffset() may therefore cause unexpected
results.
The fact that the time zone has been set to the unknown time zone is not persisted across time zone server
reboots. So it may be necessary to call this function each time the time zone
server is started. If persistence across reboots is desired the overload

This is useful when the client wants to specify the UTC time and the wall-clock offset explicitly

User::SetUTCTimeAndOffset().
If this function has been called the time zone server will use the value returned by User::UTCOffset()

results.
The fact that the time zone has been set to the unknown time zone is persisted across time zone server
reboots only if the aPersistInCenRep argument is set to ETrue. The desired offset however is never persisted
(the value returned by User::UTCOffset() is used). So it may be necessary to call this function each time
