[CONFIGURATION] btrfs snapshot timestamp does not match system date

[evinrude]

I create a btrfs snapshot with the name "snap@2020-05-23-May-1590239805" .
The last number in he name is seconds since the 'epoch' ,
Using this number I use 'date' to give me this

date --date='@1590239805'
Sat 23 May 2020 09:16:45 AM EDT

Yet if check the snap date I get this

ls -ld snap@2020-05-23-May-1590239805
drwxr-xr-x 1 root root 484 May 22 15:16 snap@2020-05-23-May-1590239805

What am I missing here ?

So I figured out that the timestamp of the snapshot tracks the timestamp of the btrfs volume .
My snap is of "/Backup2" whose timestamp is
drwxr-xr-x 1 root root 564 May 22 15:16 /Backup2

which matches the time stamp of the snapshot

ls -ld snap@2020-05-23-May-1590239805
drwxr-xr-x 1 root root 484 May 22 15:16 snap@2020-05-23-May-1590239805

I guess that makes perfect sense

Yeah, the snapshots kkep the date of the subvol. When I do mine for backup, I "touch" them to update the time to current time after taking the snapshots.
