RestrictToCategory does not work when category data is daytime

In our Web Application, I’m trying to get a data from a database using ?ReadViewEntries&RestrictToCategory=xxxx.When the first column category is date/time value in the database view, I can’t get any data from the view.

As the database is under another company’s guarantee, I can not modify the design of that.

If somebody let me know how to get data with RestrictToCategory from the daytime value category, it would be appreciated.
