# The migration would have backfilled `expire_at`
|
|
# to midnight on the 22nd of the month of the local timezone,
|
|
# storing it as UTC time in the database.
|
|
#
|
|
# If the timezone setting has changed since the migration,
|
|
# the `expire_at` stored in the database could have changed to a different local time other than midnight.
|
|
# For example:
|
|
# - changing timezone from UTC+02:00 to UTC+02:30 would change the `expire_at` in local time 00:00:00 to 00:30:00.
|
|
# - changing timezone from UTC+00:00 to UTC-01:00 would change the `expire_at` in local time 00:00:00 to 23:00:00
|
|
# on the previous day (21st).
|
|
#
|
|
# Therefore job artifacts that have `expire_at` exactly on the 00, 30 or 45 minute mark
|
|
# on the dates 21, 22, 23 of the month will not be deleted.
