Current Date and Time

Setting the current date and time is very important. The current date and time settings are used as standard timer settings for functions that require them.
Time Zone:
The standard time zones of the world are expressed globally in terms of the difference in hours (up to 12 hours) from GMT (0 hours). A time zone is a region throughout which this time difference is the same.
Daylight Saving Time:
In some countries, time is temporarily advanced throughout the summer season. This practice is called "Daylight Saving Time."
