cve-update-nvd2-native: use exact times, don't truncate

When requesting updates in a specific range, use the actual current time
and database mtime instead of truncating to midnight, and explicitly set
the timezone to UTC so that NIST don't treat the timestamps as _their_ local
time when they're _our_ local time.
