All of the internal logging goes to the file if specified, or stdout,
with the exception of a couple of serious errors, like "failed to open
the logfile". wxWidgets might be writing some of it's own logging
output to stderr though I guess.

It doesn't, as you don't typically specify absolute dates in schedule
(except sometimes for exceptions and
start/end dates - then it'll default to whatever the connection will use)

Whatever the default is for the client that causes the execution time
to be recalculated.

In truth though, when this was originally written I don't think anyone
really considered different timezones. Patches are welcome if you want
to improve.

Seemskind of silly to include a GUI library in a daemon, though I don’t doubt that it makes windows compatibility
easier.

wxWidgets isn't just a GUI library - it consists of various individual
libraries offering different features, some of which are GUI related,
and some are not. pgAgent doesn't use any of the GUI ones, so there's
no requirement to install any GUI components on your server (unless
your chosen packaging for wxWidgets doesn't separate the GUI and
non-GUI parts of course).
