Hi Chris, thanks for your hint ..
You may also be interested in http://cvs.zope.org/Products/Scheduler/ (it has a dependency on http://cvs.zope.org/Products/Event/ and a Zope
= than 2.6b1).
It relies on an external "clock" process to tickle it every so often, but you could of course kick off a Zope thread to do this...
I have looked over the sources. this Product avoids much of the trouble through calling from an external-xmlrpc-source .. that behaves like a normal http-request (auth, contexts, threading,...) I think i want a higher resolution timer with less overhead (main-loop). .. I will explore this territory during the next weeks .. thanks Ulrich Eck ------------------------------------------------------------------------ net-labs Systemhaus GmbH Ebersberger Str. 46 85570 Markt Schwaben fon: +49-8121-4747-11 fax: +49-8121-4747-77 email: ueck@net-labs.de http://www.net-labs.de
