    Some of the bigger problems we have seen:

    1. Backups expire faster than you would expect
    2. Passwords for user accounts expire. Worst case - root expires and you can't get in.
    3. Cronjobs run at odd times
    4. Log files (errpt, syslog, 'last') don't show the actual times things happened.
    5. Databases may expire "old data" too soon.
    6. Doing a find based on times (modification time, creation time) may give unexpected results. This may have an impact on scripts, especially those that clean out logs.
    7. Kerberos breaks. If you are using it, people may not be able to log in.

    You really don't want to do this on a production server.

    We found a product called "Time Machine" by SolutionSoft that allows you to change the time as seen by a user or group, rather than the entire system. So, processes running as "oracle" see a different clock than all other processes. This may be a better solution for you.
