Description

This type is a 64-bit integer representing the number of microseconds since the NSPR epoch, midnight (00:00:00) 1 January 1970 Coordinated Universal Time (UTC). A time after the epoch has a positive value, and a time before the epoch has a negative value.

In NSPR, we use the more familiar term Greenwich Mean Time (GMT) in place of UTC. Although UTC and GMT are not exactly the same in their precise definitions, they can generally be treated as if they were.
