Offset Based Time
Offset Based Time is a method of representing time using a fixed offset from Coordinated Universal Time (UTC), such as UTC+5:30 for India Standard Time. It defines time zones as static offsets that do not account for daylight saving time (DST) changes, making it simpler but less flexible than zone-based time. This approach is commonly used in systems where time zone rules are fixed or DST is not observed.
Developers should use Offset Based Time when building applications for regions without daylight saving time or in contexts where time zone rules are stable, such as financial systems or IoT devices in fixed locations. It simplifies time calculations by avoiding complex time zone transitions, reducing errors in scheduling and timestamp handling. However, it is not suitable for regions with DST or where time zone boundaries change frequently.
