One clue is that when I run `evolution` in a terminal it logs the
following error:

(evolution:4359): libecal-CRITICAL **: 17:22:46.073: 
e_cal_util_get_system_timezone: assertion 'location != NULL' failed

So my C troubleshooting skills are very rusty, but this is a learning

`strace evolution 2>&1 | grep /etc/localtime` indicates /etc/localtime
is being opened at least.

I've downloaded the source with `guix build --source
evolution-data-server`, extracted and found the the function
"e_cal_util_get_system_timezone()" at src/calendar/libecal/e-cal-util.c:1507
which calls down to "system_timezone_find()" in e-cal-system-timezone.c:522
where it looks up the timezone and compares it to a list of valid zones.

So I run `gdb evolution`, but don't seem to have the debugging symbols.
How does one get/build the debugging symbols? Can `guix build` help with

Possibly completely unrelated, but noting that both icecat and chromium
do this - which is wrong:

> new Date().getTimezoneOffset()

Where node does this - which is correct:

> new Date().getTimezoneOffset()
