Time problem - Help please

[sawagashi]

Hi all

I am currently temping for a agency and the time logging system they
use is a bit dodjy to say the least.

I log in using a e-trac asp system (their clock is fast by 5.43
mins ) and the logging is to the minute but the agency round the
time to the closest 15mins!

Can I get my exel spreadsheet to round time to the closest 15 mins

e.g. 09:00 - 09:07 = 09:00 & 09:08 - 09:15 = 09:15

Help please
as i lost half an hour of pay last week to this dodgy system

Thanks

Okay Bob, I'll confess, I was trying a different approach (much more
complicated) and I don't understand where the "96" in your formula
comes from. Can you enlighten me?

I suppose youv'e worked it out, but 24 hours times 4 quarters (24*4) = 96

Time is held as a fraction of a day, so to round to an hour, we multiply by
24, to a half-hour by 48 (24*2), to a quarter-hour by 96 (24*4). This number
is rounded, and then divided by the original multiplier to get it back to
the same scale as starting at.
