When adding new files to a module or changing files, the scm polling does't pick it up as a change.

Steps to reproduce:
1. Have a Timezone different from UTC on jenkins server.
2. change a file/add a file to module and commit.
3. run via ssh interface:

ssh jenkins build <job_name> -c

It doesn't pick up a change and doesn't start a build.

It seems the timestamp send to the cvs server are local timestamps with a
offset to UTC(GMT). The server actually expects timestamps in UTC(GMT).
