Files-snapshot date format

Greetings! I am trying to set up the files-snapshots app on my nextcloud instance. In the documentation, it suggests using a date format like this:

Y-m-d_H:i:s
if your snapshot is named like this: autosnap_2017-05-27_00:00:01_hourly

but my snapshots (done with zfstools) are in this format:
zfs-auto-snap_hourly-2017-09-06-07h00

and I cant figure out the proper date format to enter into the “date format” section of the settings to make the snapshots appear. Any ideas? Thanks!

Bumping old topic just for anyone that need help with thiese issues.

I got mine working with this config:

Basically using . as there is one in the name and * there the T is

Also use %snapshot% where your snapshots locates as described here: https://github.com/icewind1991/files_snapshots
