DESCRIPTION

This filter allow you to work with DateTime objects that represent ``Dates'', store everything in the database in GMT and not hurt yourself badly when you pull them out and put them in repeatedly.

encode

If value is a DateTime object then move it into a ``floating'' timezone and expand it into ISO 8601 format "HH-MM-SS". By storing it in the database as a floating timezone, it doesn't matter if the user's desired timezone changes between lookups

Does nothing if value is not defined or is a string.

decode

If we're loading something from a column that doesn't specify times, then it's loaded into a floating timezone.

If value is defined then converts it into DateTime object otherwise do nothing.
