Hi @santosant ,

If you are referring to the DB time that you see in the application, it will be picked up from the server time where the DB is hosted on. Depending on the OS that the DB is running on, you should be able to bypass the standard day light saving in the OS so that the time is aligned with the time used in the country. 

The setting would look something similar to below (this is from Windows 2016)

Cheers

I think you are looking for the Time Zone Offset function, on each site there is a Time Zone Offset in relation to the server.  Depending on the server time zone compared to the site time zone, you might need to make an adjustment to this value to have the timestamps for transactions be accurate.
