How it works

Sum nonnegative decimal values with their unit scales. A month is 30.44 days and a year is 365.25 days.

2h 30min = 7200 + 1800 = 9000 seconds.

Limits

Nominal duration syntax only, up to 10¹² seconds. Nanoseconds and infinity are recognized; individual systemd directives can accept a narrower syntax or use a different default unit.
