reset file modification time when go back in time?

[dhruva]

Hi,
 I am using mercurial to maintain my local changes of fairly large
projects. I use branches and MQ quite extensively. The problem I face
when I change between branches is the modification in the file
timestamps. Whenever I switch a branch, the build system recompiles
the whole stuff.
 I was wondering if the last modification time for each file in a
changeset be stored and restored when the changesets are applied back?
This would prevent the recompilation/build of projects.
