Revert "lib/, src/: Use local time for human-readable dates"
This reverts commit 3f5b4b56268269fefed55aa106f382037297d663.
Time-zone conversion of day-precision timestamps is lossy. Since the
timestamps are stored as UTC, let's print them as UTC. That allows
users to see the actual value that is stored, and thus the value that
would be used for comparison, for example for deciding if a login is
valid.
In the following commit, we add time-zone information to the strings,
which should allow users understand any discrepancy between the date
input (by default in local time), and the printed one (always in UTC).
lib/time/day_to_str.h: day_to_str(): Print time-zone information together with dates
We print dates as UTC dates, but unqualified dates are understood to be
in local time. Thus, we need to expressely mark them as UTC dates.
In ISO mode, append a 'Z' without space. In the current locale, since
we don't know the format, append the ' UTC'.
