I have a box that is shared amongst multiple users and I need to force all login's to use 24 hour time. I am admin on the box but I don't have access to group policy's or the actual users themselves. I would like a solution that would work for any user who logs in, not just a preset list of users. I tried looking around for a command line process that I could put in the startup folder but I couldn't find anything. I modified the date time settings for myself hoping that it would propogate down to all users but it didn't. Please provide some direction.
