Questions

What is a Unix timestamp?

The number of seconds since 1 January 1970 00:00:00 UTC (the Unix epoch), ignoring leap seconds. It is the same everywhere in the world at a given moment.

How is IST related to UTC?

Indian Standard Time is UTC + 5 hours 30 minutes all year round — India does not use daylight saving time.

Seconds or milliseconds?

Unix tools and most APIs use seconds (10 digits today); JavaScript and Java use milliseconds (13 digits). This converter detects which one you pasted.
