. at Bob,

I read the request as asking for a way to present the local time (wall
clock) when the system time s set to UTC.  In other words, the default
presentation of time (UTC) is say 1PM and the offset from UTC for the
location is +2 hours, then the wall clock time is actually 3PM.  The
system shows the time as 1PM and the utility being requested should
show 3PM.
