As it turns out, the GDateTime was introduced in 2.26 but not the
iso8601 function.
changes since v3:
- rename the functions
- dropped useless wrapper around gettimeofday()
changes since v2:
- moved new code into util helper file
- updated wifi plugin as well
changes since v1:
- added error handling
- use gettimeofday() like Glib does
- backwards compatibility added to string parser
Daniel Wagner (4):
util: Add timestamp helpers
service: Remove GDateTime API usage
wifi: Replace GDateVal API usage
tools: Remove GDateTime API usage

New subject: [PATCH v4 1/4] util: Add timestamp helpers
Use POSIX APIs to implement a simple replacement for GDateTime.
The Glib code uses gettimeofday() to implement g_date_time_new_now(),
so use the same interface to avoid breakage.
Furthermore, the Glib code writes the timestamps with sub seconds
values, e.g. "2019-10-20T14:45:31.079935Z". The new code only writes
with second precision. That means the string parser needs to be able
to deal with the old time and new format.
