Consider the timestamps in Exim's log files, though nowadays you can, in
fact, get the timezone included there too, of course.

Normally, if you set your timezone and then build Exim, it will use that
timezone.

In some operating systems, but alas not all, setting timezone to an
empty string means "wallclock time". If this is the case on your system,
you should do that in your Exim config. It would be really good if this
were universally true.

But in practice, how often does an MTA move to a different timezone?
