Typeahead problem with DATE types

Hi Guys,

I have a form with an element of type typeahead. The Dataprovider of the field is of a type Date. I have a value for the field which simple has has the following values in it:
00:00
00:15
00:30

24:00

when I click on the field in the form, it will bring me a list like the following:

1970-01-01 00:00:00.00
1970-01-01 00:15:00.00

1970-01-01 24:00:00.00

I have already change the filed format to: HH:mm|mask
which is supposed to show me the list without the dates but for some reason it brings the list with all those information that I don’t want!

Is there anyway to filter the list out to show me what I want:
00:00
00:15

24:00

or at least I can change the dates to show current date not 1970-01-01!

Cheers,
Siavash
