For half-hourly or hourly snapshots, you can choose how many minutes after the half-hour

snapshot is taken, and for weekly or monthly snapshots, you can specify the day, hour, and
minute.

Scheduling Snapshots (CLI)

Use the following procedure to configure automatic snapshots of a share and set a retention
policy for those snapshots.
Automatic snapshots can be taken half-hourly, hourly, daily, weekly, or monthly and are named
.auto[-<snaplabel>]-<timestamp>. Snapshot creation times are stored and executed in UTC
format, without regard to such conventions as daylight saving time. For example, a snapshot
scheduled for 10:00 a.m. PST (UTC-8) is stored and executed at 18:00 UTC, and this is the time
that will appear as the timestamp in the snapshot name.
Automatic snapshots can be set on a project or a share, but not both. Otherwise, overlapping
schedules and retention policies would make it impossible to guarantee both schedules.
Removing an interval, or changing its retention policy, will immediately destroy any automatic
snapshots not covered by the new schedule. Automatic snapshots with clones are ignored.
