`time` converts a timestamp string with an optional default location into a [`time.Time`](https://godoc.org/time#Time) structure so you can access its fields:
|
|
|
|
```go-html-template
|
|
{{ time "2016-05-28" }} → "2016-05-28T00:00:00Z"
|
|
{{ (time "2016-05-28").YearDay }} → 149
|
|
{{ mul 1000 (time "2016-05-28T10:30:00.00+10:00").Unix }} → 1464395400000, or Unix time in milliseconds
|
|
```
|
|
|
|
## Using locations
|
|
|
|
The optional `TIMEZONE` argument is a string that sets a default time zone (or more specific, the location, which represents the collection of time offsets in a geographical area) that is associated with the specified time value. If the time value has an explicit timezone or offset specified, it will take precedence over the `TIMEZONE` argument.
|
|
|
|
The list of valid locations may be system dependent, but should include `UTC`, `Local`, or any location in the [IANA Time Zone database](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones).
|
|
|
|
If no `TIMEZONE` is set, the `timeZone` from site configuration will be used.
|
|
|
|
```go-html-template
|
|
{{ time "2020-10-20" }} → 2020-10-20 00:00:00 +0000 UTC
|
|
{{ time "2020-10-20" "America/Los_Angeles" }} → 2020-10-20 00:00:00 -0700 PDT
|
|
{{ time "2020-01-20" "America/Los_Angeles" }} → 2020-01-20 00:00:00 -0800 PST
|
|
```
|
|
|
|
## Example: Using `time` to get month index
|
|
|
|
The following example takes a UNIX timestamp---set as `utimestamp: "1489276800"` in a content's front matter---converts the timestamp (string) to an integer using the [`int` function][int], and then uses [`printf`] to convert the `Month` property of `time` into an index.
|
|
|
|
The following example may be useful when setting up [multilingual sites][multilingual]:
|
|
|
|
{{< code file="unix-to-month-integer.html" >}}
|
|
{{ $time := time (int .Params.addDate)}}
|
|
=> $time = 1489276800
|
|
{{ $time.Month }}
|
|
=> "March"
|
|
{{ $monthindex := printf "%d" $time.Month }}
|
|
=> $monthindex = 3
|
|
{{< /code >}}
