Buid schedule doesn't kick off or email notification doesn't go

To troubleshoot, does the build start from the build definition when requested manually with the build engines running? If email notification is configured and running otherwise in your Jazz environment I would guess it was not sent since the build never kicked off.
Are your JTS and /ccm in a distributed topology? Sharing a time server for synchronized time? How about the machine on which your build engine is running?
