Round down for time

[Guest]

Can someone provide a formula to use for rounding down time data.
Example 9:37 needs to round down to 9:30 and 7:25 needs to round down to 7:00.

Thanks - in advance...!!!

=FLOOR(A1,TIME(0,30,0))
And format as time.

Your examples are rather ambiguous, but I'll assume you want to round
down to the nearest half-hour:

=FLOOR(A1,"00:30")

or, since XL stores times as fractional days, equivalently

=FLOOR(A1,1/48)
