Date of payment vs date of deduction vs date of deposit

This question is with reference to Form 24Q. I want to be clairified on the difference between these different dates in the scenario given below
The Andhra Pradesh State govt. employees get  a month's salary on the first working day of the next month ( not on the last date of the same month like central govt. employees). And Tax is deducted by book adjustment.
Now, suppose an employee gets december-2014 salary on 01-01-2015 please suggest the correct way to fill the following dates on Annexure -I of Form-24Q (using NSDL's RPU):
Date of Payment/credit of tax
Date of Deduction of tax
Date of Deposit of tax
