[Feature Request] Add an method to set timezone

[recolic]

Maybe like this:

loc, _ := time.LoadLocation("Asia/Taipei")
ctab.SetLocation(loc)

https://golang.org/pkg/time/#Time.In

Hi,

Being able to set on UTC+0 would be great. Having a Cron depending on the local time of the server can be tricky when deploying across multiple areas.

@mileusna any thoughts on the @recolic 's issue?

Thank you,

[sneko]

For other reasons (needed some features) I switched to https://github.com/go-co-op/gocron which also allows specifying the timezone while accepting schedule expressions.

Thanks @mileusna for your work!
