[seam-dev] Seam Cron API for scheduled .... things

[Peter Royle]

JSR-310 looks useful for defining the current time on the payloads that get fired, which is part of the external API. I think that's about it so far. So considering JSR-310 is alpha, is it still advisable to use that project as part of my API?

Does anyone else on this list use that project for anything? Please let me know.
