It requires newer glib than we do:
6413ff
6413ff
  ../libmm-glib/mm-common-helpers.c: In function ‘mm_new_iso8601_time’:

   1787 |         tz = g_time_zone_new_offset (offset_minutes * 60);

Let's not use the routine as opposed to bumping our requirement so that
6413ff
we don't lose ability to build on CentOS 8.
