Web devs: Is there a software alternative to Cron Jobs?

[RayB]

My web host doesn't provide "cron job" service. I was wondering if there was such a thing as something I could install (php, cgi,  ...) which does the same as cron? (No, I don't have root access... its shared hosting).

All I've found is online services, but I'm not comfortable with supplying them with the username, password, database info.

google for "php job scheduler" turned up this:

If you have java capability, quartz is excellent:
