Time-Based Trigger - Reset a Sequence at a certain time

Here's my problem:

Sequence from 1 to ~
Create a unique identifier by:

But then I want to reset the sequence to 1 on Jan 1st (or some other time)every year.
Or if possible, how about more flexibility on when the sequence reset is triggered (in case I modify the unique identifier to monthly, weekly)?

How do I go about creating a time-driven trigger rather than a data-driven trigger or event-driven trigger?

Thanks for your help.

Nevermind, I've got it figured out.
