Yes I was referring to the Perl DateTime module. But I'm not stuck on using that. My problem is this.
1. I must use the epoch 2000 Jan 1, 12:00:00 (UTC) That's 12noon.
2. From that epoch I will be given both beginning and end time boundaries in the future.
3. I will need to add/sub seconds from either of those boundaries.
4. Then convert back to readable form in UTC.
