Topic: duration

• Duration and interval strings: ISO 8601, Go's ParseDuration, systemd, Prometheus, PostgreSQL and .NET TimeSpan

  PT1H30M, 1h30m, '1h 30min' and 01:30:00 can all describe the same span of time, but each parser accepts a different alphabet of unit suffixes and rejects everything else, so a duration string copied between systems often simply fails to parse.
