[CentOS] Any reliable way to determine LVM snapshot creation time?

We utilize LVM snapshots for some periodic maintenance. They're
manually created and, usually, manually destroyed.
But not always.
So there's now a nightly script monitoring for open snapshots.
Which raises the question of when a given snapshot was created.
Absent good practices of, say, using sudo to create snapshots (leaving a
/var/log/secure message), is there any reasonably reliable way to
determine when an LVM was created?
There's a timestamp on the /dev/mapper/<snapshot> file. I'm presuming
that's somewhat useful for this purpose?
Ah: just found /var/log/messages also indicates:
lvm: Monitoring snapshot <name>
lvm: No longer monitoring snapshot <name>
... which I think answers my own question. Posting here for Google's
sake and/or discussion.
