Comparing Date/Time Columns

Hi,

I have 4 Date/Time columns->[ShiftInTime] [ShiftOutTime] [TimeFrom] [TimeTo]

I am trying to count the total number of times [ShiftInTime] & [ShiftOutTime] is equal to [TimeFrom] & [TimeTo] (and the number of times it's not)

I am using this calculated column -> Clocked in by office = IF(Query1[ShiftInTime] && Query1[ShiftOutTime] = Query1[TimeFrom]&&Query1[TimeTo],TRUE(),FALSE())

I am not getting any syntax errors but I know the numbers returned are not right.
