Jifty::DBI::Filter::Date - DateTime object wrapper around date columns
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.
If value is a DateTime object then move it into a "floating" timezone and expand it into ISO 8601 format
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.
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.
