XCON: GMT Offset Not Calculated By Some Messaging Systems

• Microsoft Exchange Server, versions 4.0, 5.0, 5.5

SUMMARY

When sending a message with a Read Receipt (RR) request from a third-party messaging system to Exchange Server, the RR reply may contain the Greenwich Mean Time (GMT) and not the correct GMT-offset time.

MORE INFORMATION

When Exchange Server processes a Read Receipt request, it sends the RR reply back with the time stamp in the YYMMDDHHMMSSZ format.

The 'Z' at the end signifies GMT. It is then up to the receiving client or MTA to add the adjusted offset time to the GMT to allow proper conversion to the local time-zone.

If they do not adjust the GMT offset, they will simply display the GMT time stamp.

This may also occur with Message Expiration requests or any other type of request embedded in the P2 of a message.

Delivery receipt requests usually will not display this behavior because the Exchange Server MTA encodes the GMT offset into the P1 when sending the report back.

This behavior is by product design.
