commit 8661af798(timeval: Provide a variation for time/warp command) provided a variation of time/warp command to prevent multiple invocations of time/warp. That commit changed only the users in bfd.at and cfm.at as they used it the most. Since we haven't had any negative confequences because of the change, add the remaining users.
