Duration

Durations are represented as a number with a time unit suffix. A value without a suffix is interpreted as seconds, and fractional values (e.g. 1.5h) are accepted.

Supported time units are:

Time Unit	Identifier	Calculation
Nanosecond	ns	1
Millisecond	ms	1000000
Second	s	1s
Minute	m	60s
Hour	h	60m
Day	d	24h
Week	w	7d

Microseconds are also supported, spelled Ms (capital M, lowercase s).

Month and year units are not supported — their length is ambiguous, so express longer intervals in weeks or days.

Example

# 1 second
