What is the difference between each time zone?
Each of the 24 zones of the Earth is one hour ahead of the one to the east, which equates to about 15 degrees of longitude for each. Although this is the general rule, there is not always a difference of one hour between each time zone. Some countries have adopted a non-standard time, which may include a delay of 30 or 45 minutes.

What should be the timezone of the server?
The time spent to the cloud server by the underlying hardware is generally expected to represent UTC +0000 by the operating system. Therefore, for most server operating system settings, it is recommended that you select the UTC time zone at the hardware level, and then set the local time in the operating system settings.
Should I use UTC GMT?
UTC is also more closely tracked as official time (ie it is more in line with “true” time based on the rotation of the earth). But unless your software needs calculations to the second, it shouldn’t make a difference whether you use GMT or UTC. Although, you might consider which one to display to users.
What is the importance of the time zone?
A time zone is a region of the world that observes a uniform standard time for legal, business, and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions rather than longitude, because it is convenient for areas in close commercial or other communication to keep the same time.
Is EST the same as GMT?
When converting from EST to GMT, there is a difference of five hours. If it is 12 am Eastern Standard Time, then it will be 5 am Greenwich Mean Time. During the summer months, the time change causes a difference of four hours between the two, since the East area is one hour ahead in spring.
