`time.Duration` converts a given number into a [`time.Duration`](https://pkg.go.dev/time#Duration) structure so you can access its fields. E.g. you can perform [time operations](https://pkg.go.dev/time#Duration) on the returned `time.Duration` value:
|
|
|
|
{{ printf "There are %.0f seconds in one day." (duration "hour" 24).Seconds }}
|
|
<!-- Output: There are 86400 seconds in one day. -->
|
|
|
|
Make your code simpler to understand by using a [chained pipeline](https://pkg.go.dev/text/template#hdr-Pipelines):
|
|
|
|
{{ mul 7.75 60 | duration "minute" }} → 7h45m0s
|
|
{{ mul 120 60 | mul 1000 | duration "millisecond" }} → 2h0m0s
|
|
|
|
You have to specify a time unit for the number given to the function. Valid time units are:
|
|
|
|
Duration|Valid time units
|
|
:--|:--
|
|
hours|`hour`, `h`
|
|
minutes|`minute`, `m`
|
|
seconds|`second`, `s`
|
|
milliseconds|`millisecond`, `ms`
|
|
microseconds|`microsecond`, `us`, `µs`
|
|
nanoseconds|`nanosecond`, `ns`
