Page to set up date and time is obviously an important tool of any website. Everything should be fixed in time: deal lifetime, order creation, subscription time, newsletters schedule etc. To avoid any confusions and misunderstandings we recommend you to make sure date and time are set up correctly on your website.
On Date and Time tab you can set Time zone and choose the formats for date and time displayed for your convenience. The default timezone is GMT, so if you are located in other timezone, it can be changed on this tab.
When it is done, do not forget to save the changes.
