Simplest way: Simplest way:
... nextTime := cronexpression.NextTimeFromCronString("0 0 29 2 *", time.Now())
nextTime := cronexpression.NextTimeFromCronString("* * 29 2 *", time.Now())
Assuming `time.Now()` is "2013-08-29 09:28:00", then `nextTime` will be "2016-02-29 00:00:00".
If you need to reuse many times a cron expression in your code, it is more efficient
to create a `CronExpression` object once and keep a copy of it for reuse:
cronexpr := cronexpression.NewCronExpression("0 0 29 2 *")
nextTime := cronexpr.NextTime(time.Now())
Assuming *time.Now()* is "2013-08-29 09:28:00", then *nextTime* will be "Monday, February 29, 2016 00:00:00".
