If your find doesn't have the -mmin or -daystart primaries (neither of which are specified by the standards), you can also use touch to create two files with the timestamp boundaries you want at each end of your window and use:

Code:

trap 'rm -f /tmp/start_time_file.$$ /tmp/end_time_file.$$' 0

# Note that although the following uses midnight as the start and stop times,
# using touch allows you to set any time range you want.  If you use -d instead
# -t to set timestamps, you can set ranges down to the nanosecond level if the
# filesystems on which the time range files and the file hierarchy being searched
# support timestamps to that level of detail.
touch -t 201802050000 /tmp/start_time_file.$$
touch -t 201802080000 /tmp/end_time_file.$$

find /directory/at/root/of/hierarchy -type f -newer /tmp/start_time_file.$$ ! -newer /tmp/end_time_file.$$

Note: Fixed to consistently use timestamp files created in /tmp and switch end and start files in the find command as noted by RudiC in private mail.
