/*
Package gocronexpr implements cron expression parser and calculate next execution time.
The pattern is a list of six single space-separated fields: representing
second, minute, hour, day, month, weekday. Month and weekday names can be
given as the first three letters of the English names.
Example patterns:
- "0 0 * * * *" = the top of every hour of every day.
- "*\/10 * * * * *" = every ten seconds.
- "0 0 8-10 * * *" = 8, 9 and 10 o'clock of every day.
- "0 0 6,19 * * *" = 6:00 AM and 7:00 PM every day.
- "0 0/30 8-10 * * *" = 8:00, 8:30, 9:00, 9:30, 10:00 and 10:30 every day.
- "0 0 9-17 * * MON-FRI" = on the hour nine-to-five weekdays.
- "0 0 0 25 12 ?" = every Christmas Day at midnight.
Usage:
cronExpr, err := New("* * * * * *", time.Local)
if err != nil {
fmt.Println(err)
return
}
nextTime, err := cronExpr.Next(time.Now())
if err != nil {
fmt.Println(err)
return
}
fmt.Println(nextTime)
