Rounding time according to entry in a cell

I have developed the following formula-

=IF(F3="","",IF(E3>="*06",ROUND(F3*96,0)/96-1/96,ROUND(F3*96,0)/96))

Which is designed to take a time in from D2, a time out from E3 and return the time difference, rounding down to the nearest ¼ hour if it is six or less minutes past the hour, and rounding up if it is seven minutes or more past the hour; it works perfectly well from 01 to 06 minutes past the hour, rounding down as it should. It works perfectly well from 08 minutes past the hour, rounding up as it should. However, for 07 minutes past the hour it is supposed to round up, but instead rounds down. Can anybody see my mistake?
 
IF(E3>="*:06", is always evaluated by Excel as FALSE so the 2nd formula in the IF statement is always being used.

I'm glad Barry's last formula gave you the results you wanted. I'm curious though why sometimes you'd use 6 minutes after the quarter hour and sometimes 7 minutes. For example:
6 is 6 minutes after the top of the hour
22 is 7 minutes after 15 minutes past the hour
36 is 6 minutes after 30 minutes past the hour
52 is 7 minutes after 45 minutes past the hour

Did you know Excel offers Filter by Selection?
Add the AutoFilter icon to the Quick Access Toolbar. Select a cell containing Apple, click AutoFilter, and you will get all rows with Apple

company decided they would do it. Six minutes after the hour and half hour reverts to the previous quarter hour; seven minutes past the quarter hour reverts to the previous quarter hour. If you saw my shift pattern, you might think it was deliberately designed to keep us guessing. I suspect whoever came up with both ideas was either very stupid or very clever!

Barry’s solution now allows me to calculate paid hours and with a little maths I can have Excel calculate my gross pay for the week; a bit more work, and my net pay. Anybody understand the UK tax and National Insurance system? Just joking!
