If you are running a dedicated hosting server and you come across a situation where you see that the date time of the server is showing a time different from your regional timezone then you can change it easily from your WHM panel.
Login into your WHM panel and then search for Server in the search box on the left sidebar.
As soon as you type it you will see that Server Time comes up in the results below. Click on the Server Time link and you will arrive at the next page which shows the current time of the server and the timezone.
Now expand the drop down and search for your timezone from the list of time zones available on your server.
Once you have selected your timezone then click on the Change Timezone button on the right. The update usually takes a couple of seconds and then WHM displays the confirmation page showing that it has changed the timezone.
Now the time on your server should be the same as your timezone. Hope the above helped!
