  Date/Epoch Functions
  Author: Thomas Ballard (http://thomas.ballard.ws)
  Copr. 2002-2008, E.S.Q. Software

  Note: slightly polluted to attempt to support a GMT/non-GMT (local) timezone offset feature. 
  Hack and slash resulted in a form input having a toggle state... but these functions need 
  to know that form and input to access the property for evaluation. Need to come back 
  and make these methods more agnostic.
