I have done a bit of thinking about this. On reflection, it seems to me
that flattening the environment was a bad idea, and should be removed.
You never know what settings might be required in some OS.
That leaves the problem of the timezones. I now have a new proposal:
. There is an Exim option called tz, which can be used to set a
. The value of tz defaults to the setting of TZ when Exim is built.
. In any Exim run, if timestamps_utc is not set, Exim compares the
setting of TZ with the setting of tz.
. If they are different, it makes a copy of the environment, leaving out
any existing TZ setting, and adding (if necessary) the required TZ
. This copy is then used from then on.
It seems to me that this scheme will work in all operating systems. The
HANDS_OFF_ENVIRONMENT compiler macro can be abolished.
