I have created simulation channel and started logging in the SQL using DSN.
However, the logging interval condition is 1 minutes. 
TImestamp is used for System.
I facing issue that ms timestamp is increasing sometimes, and after few hours it will increase in 1 sec.

Please take a look at the Kepware knowledge article in the following link:

 

Article - CS305780 - Which timestamp does the DataLogger plugin write to the database in PTC Kepware Products

 

You may need to create a free my kepware account to access the article with those login credentials.

 

You may need to change your trigger conditions, If the change does not correct the issue, I recommend opening a support ticket with the Kepware team. Here is a link to the login page where a ticket can be opened:

There is a start and stop time to these triggers, If it hasn't stopped in time it wont start again. 

when I first used KW a dozen years ago I had a lot of trouble using time based triggers, what I wound up doing was creating a log group that consisted ONLY of time based triggers that fires at minute 0.,  Minute 5 etc and then used THOSE to trigger other groups that logged actual data.
