view changesets between 2 dates

There isn't one command to do what you want.

It sounds like the 'list changeset' command would be of use to you to get the change sets. You can specify change sets created before and after a certain date. Once you have that list of change sets, you can inspect them with the 'list changes' command. You can also use the 'list states' command to see when the last check-in occurred for a more specific date.
