go-datemath

This library provides support for parsing datemath expressions compatibly with Elasticsearch datemath expressions. These are useful for allowing users to specify, and for encoding, relative dates. Examples:

• now+15m: 15 minutes from now
• now-1w+1d: one day after on week ago
• 2015-05-05T00:00:00||+1M: one month after 2019-05-05

These expressions will seem familiar if you have used Grafana or Kibana.

Example usage:

expr, _ := datemath.Parse("now-15m")
fmt.Println(t.Time(datemath.WithNow(now)))

See package documentation for usage and more examples.
