I do not think that is a jammer unless it was placed on my van.
Today the offset changed.
The minutes remained at 40 but the hours changed.
I have opened a ticket with Magellan about this.
I am not real happy with their products, the POI database was wrong
right after an update and they will not release a tool to correct this.
This database is XML so tools do exist.
I am waiting for their reply to this ti\me decode issue before I start
changing database entries.
It still navigates well and I have been able to change time zones so
that the time is now only 10 minutes off.
I think that I set GMT offset to plus 5.5 hours where it should be - 5
hours.
I do not know of a way to display day number on this device.
That may be a clue, if I can get it to display date.
Thanks for the information.
I will continue to pursue this with Magellan and let the group know
their answer.
I might be a hardware failure in my unit, but, I do not think so.

Did anything happen in the last 24 hours that would affect the time
displayed on a gps receiver?
I have a Magellan RoadMate RM9612T-LM that started displaying time that
is one hour and 40 minute in the future.
I have verified that the correct time zone is selected.
I changed the time zone and it displayed time for that zone with the
same offset.
I am in eastern zone and have set receiver back to auto with same
results.
Thanks

===================================
Glenn,
All but one of my GPS devices survived that, but in the one which did
not (a GT-730FL-S USB logger) /only/ the day number was affected, and
not the time of day. The dates were 1999-09-15 onwards. I wrote a
simple program to correct the GPX files the device's program (Canway)
produced.
Glen's issue may be related to WNRO, but it's not the same symptoms
I've seen. Any chance there's someone local with a new (pretty
advanced) jammer? Hope it's resolved soon.
Cheers,
David
