Time Zone Distinction: The time zone distinction between two areas is the variety of hours (and typically minutes) by which their commonplace occasions differ.
Calculating Time Conversion: To transform time from one time zone to a different, you should utilize the next formulation:
New Time = Present Time ± Time Zone Distinction
(+) for changing from a later time zone to an earlier time zone
(-) for changing from an earlier time zone to a later time zone
Daylight Saving Time (DST) Adjustment: When changing time during times when DST is in impact, you might want to regulate the time distinction accordingly.

Examples of Time Conversion:

To transform 10:00 AM in UTC to Pacific Commonplace Time (PST), we subtract 8 hours: 10:00 AM UTC – 8 hours = 2:00 AM PST.
To transform 7:00 PM in Japanese Commonplace Time (EST) to Central European Time (CET), we add 6 hours: 7:00 PM EST + 6 hours = 1:00 AM CET (subsequent day).
When DST is in impact, the time distinction could change by one hour. For instance, throughout DST, 11:00 AM in EST could be transformed to 4:00 PM in British Summer time Time (BST) as a substitute of three:00 PM.
