you can eliminate duplicates by creating a query and set its property to
UNIQUE VALUES = TRUE.

another query, Max ,Min , turn on summations....
pick: EMP, Format([StartTime], "mm/dd/yy") as StartDte, MIN(Format([StartTime], "hh:nn:ss")) as StartTime ,MAX(Format([EndTime], "hh:nn:ss")) as EndTime

can they not clock in/out more than once a day?
do you have night shift. clock in today/out tomorrow?
do you really get multiple clock ins timed exactly the same?

If the latter, then I would check the clock in activity, and the process, rather than disregard the data.

personally, I would run a validation to look for problems.

ie, 2 successive events of the same type. A clock in, followed by another clock in, with no clock out.
