+# Note here that the POSIX notation is a bit weird.
+# The libc documentation shed some light on this:
+#  The offset specifies the time value you must add to the local time to get a
+#  Coordinated Universal Time value. It has syntax like [+|-]hh[:mm[:ss]]. This
+#  is positive if the local time zone is west of the Prime Meridian and negative
+#  if it is east. The hour must be between 0 and 24, and the minute and seconds
+#  between 0 and 59. [1]
