Outside of Xcode, when I run the program (a "Command line tool") directly from
the bash shell, it prints out in UTC "unixy" format:
2019-08-31 01:00:01 +0000
...but at the same time it gets logged in the Console log as:
Fri Aug 30 18:00:01 2019
Same result if I run it as a system daemon. So as you suggest it seems there
could be some sort of environment sensitivity going on. If only I knew what env
var to set in the shell... UTC really isn't what I'm looking for.
