Date Time

Various operators for parsing and manipulating dates.

Date time formattings

This uses the golangs built in time library for parsing and formatting date times.

When not specified, the RFC3339 standard is assumed 2006-01-02T15:04:05Z07:00 for parsing.

To specify a custom parsing format, use the with_dtf operator. The first parameter sets the datetime parsing format for the expression in the second parameter. The expression can be any valid yq expression tree.

yq 'with_dtf("myformat"; .a + "3h" | tz("Australia/Melbourne"))'

See https://pkg.go.dev/time#pkg-constants for examples of formatting options.

Timezones

This uses golangs built in LoadLocation function to parse timezones strings. See https://pkg.go.dev/time#LoadLocation for more details.

Durations

Durations are parsed using golangs built in ParseDuration function.

You can durations to time using the + operator.
