I haven't opened your file, but:
Formula:

will always round down to the nearest 15 mins, and
Formula:

will always round up.

Hi benoj2005,

Try using below formula:-

=MROUND(I16,0.0104166666666667)

where I16 cell has the time

Slight amendment:
Formula:
`Please Login or Register  to view this content.`

is required if the time to be rounded down is only a few minutes after midnight.

That causes the total for the day to change to #####

That works for clock IN's but not for Clock OUT's, which need to round DOWN, not UP

You have 00:00-15:15, which may look fine to us humans, but for Excel it results in a negative time, which it cannot handle. To get around this, you would have to add 1 day when "Interval Out" is greater than "Interval In". i.e. when the shift goes over into the next day. Try this in C9:
Formula:
`Please Login or Register  to view this content.`

and, of course, this in C10:

Thanks, that worked.

You'd think they'd have some functions for dealing with time like this.

All sorted, solution here if anyone wants for future Hours Totals & Rounding.xlsx
