Currently, Prometheus template functions include
parseDuration, which parses a duration string (e.g."1h2m10ms") and returns the total duration in seconds as a float. However, it is often more useful to work directly with Gotime.Durationobjects ortime.Timeoperations in templates for alerting and logging purposes.For example, in Loki alerting, when adding a
ActiveAt(need add to Loki) function for alert start time, usingparseDurationTimeallows returning the time in the needed format, such as:Adding parseDurationTime enhances Prometheus templating by providing rich duration/time operations in templates, improving alerting capabilities with use cases in Loki.
