I'm not sure what you mean by "files which fall between two dates". With Perforce's atomic change transactions it's easy to get the state of files as of a certain time. Running

p4 sync @change-number

will give you the state of all depot files mapped to that client as of that change number. You can also, of course, limit which files you synchronize (update/delete) with

p4 sync //depot/foobar/... at change-number

Unless you've done something wacky (editing the dates by hand or setting the clock on your server back in time) change numbers increase monotonically with time.

I wrote a very simple Perl script which, given a date, takes the output of p4 changes and returns the change number in effect at the start of that day. The script is called p4dtc (date-to-change). Thus, for example, you can type

p4 sync @`p4dtc 1998/1/1`

to get the state of the depot at the stroke of midnight on New Years'. To compare this with the state on, say, Feb 14, run

p4 diff @`p4dtc 1998/2/14`

The script is available from http://www.perforce.com/perforce/loadsupp.html
