Following is a list of country codes, their timezone identifiers, the timezone offset in each of these regions with respect to UTC, and the standard Timezone abbreviations for each location. These are very useful when you want to convert the time object value in a specific time zone to a time object value in a different time zone.
For reference, TZ stands for time zone, UTC stands for Coordinated Universal Time, STD stands for standard time and DST stands for Daylight Savings time.
