* D => Short names of days
* l => Long names of days
* d => Day numbers
* M => Short names of months
* F => Long names of months
* m => Month numbers
* Y => Four digit year
* y => Two digit year
* h => 12 hour format
* H => 24 hour format
* i => Minutes
* s => Seconds
* a => am/pm
* A => AM/PM
* </pre>
* - 'minYear': Minimum year in year select
* - 'maxYear': Maximum year in year select
* - 'addEmptyOption': Should an empty option be added to the top of
* each select box?
* - 'emptyOptionValue': The value passed by the empty option.
* - 'emptyOptionText': The text displayed for the empty option.
* - 'optionIncrement': Step to increase the option values by (works for 'i' and 's')
* - 'minHour': Minimum hour in hour select (only for 24 hour format!)
* - 'maxHour': Maximum hour in hour select (only for 24 hour format!)
* - 'minMonth': Minimum month in month select
