 Please can you help on this, I want to group this date modified into three different groups like, from 6.00 am to 1.59pm and 2.00pm to 9.59pm and 10.00pm to 6.00am

@krish86 Here is one way by using a calculated column. The trick I used is to first add 6 hours to the date+time so your periods start at midnight. Then divide by 3 and take the integer of that so we get three "periods" of 8 hours in a day and finally, subtract the six hours again to shift the time back to its "original" period. See attached.
