Date or Time From/To

I have a filter that allows the user to specify a date/time from/to within one field. The field has a popup calendar that enables date selection and right below the calendar, still in the same pop up, the user has some time selection as well.

For the label for this field, I'm not sure whether to call it "Date From" and "Date To" or "Time From" and "Time To".

I supposed there is also the option to have both "Date/Time From" and "Date/Time To" but I'm not sure if that is as clean.
