Tamperproof expired snapshot behaviour during DST time change

Hi all,

 

I have configured a Tamperproof Snapshot with snaplock. 

 

During DST time change from summer to winter time (-1 hour), NTP server update time to ONTAP.

After getting new time, the least tamperproof snapshot has suddenly expired and deleted after creating a new one by scheduler.

 

Is this the expected behaviour during Daylight Saving time change to get one TPS suddenly removed ?

When the next DST time change from winter to summer occur, will we get more snapshot keeped by system due to time change (+ 1 hour) ??

 

I have found no KB explaining this expected behaviour.

 

Thanks for your help.

Vincent
