Go: Parsing Time Expressions

go-time-parse will parse time expressions into time.Duration quantities. From the example:

actualDuration, phraseType, err := ParseDuration("24 days from now")
log.PanicIf(err)

fmt.Printf("%d [%s]\n", actualDuration/time.Hour/24, phraseType)

actualDuration, phraseType, err = ParseDuration("now")
log.PanicIf(err)

fmt.Printf("%d [%s]\n", actualDuration, phraseType)

actualDuration, phraseType, err = ParseDuration("12m")
log.PanicIf(err)

fmt.Printf("%d [%s]\n", actualDuration/time.Minute, phraseType)

actualDuration, phraseType, err = ParseDuration("every 6 hours")
log.PanicIf(err)

fmt.Printf("%d [%s]\n", actualDuration/time.Hour, phraseType)

Output:

24 [time]
0 [time]
12 [interval]
6 [interval]
