Server Crontab will be updated soon depending on the input I get over on the official SourceMod forums.
Planning to recode the job scheduler to use more UNIX like job formats which should make everything much more easier for server admins. Had another idea to make extensions that revolve around the scheduler – Take for example a server cleanup that runs every morning at 6am, the plugin alone would be useless because anyone with RCON will have to run it manually, but using Server Crontab that task can be fully automated.
