Module DurationSource

Duration - conversions to various time units

A duration is represented in nanoseconds as an unsigned 64 bit integer. This has a range of up to 584 years, or 213503 days, or 5124095 hours, or 307445734 minutes, or 18446744073 seconds, or 18446744073709 milliseconds, or 18446744073709549 microseconds.

All functions converting to t raise Invalid_argument on out of bound or negative input.
