Cron.go

This is a simple library to handle scheduled tasks. Tasks can be run in a minimum delay of once a second--for which Cron isn't actually designed. Comparisons are fast and efficient and take place in a goroutine; matched jobs are also executed in goroutines.

For instance, you can use the following in your web application that uses MySQL:

func init() {
  cron.NewWeeklyJob(1, 23, 59, 59, func (*time.Time) {
    _, err := conn.Query("OPTIMIZE TABLE mytable;")
    if(err != nil) { println(err) }
  })
}
