Cron value discrepancies

[jimtng]

The openhab docs here: https://www.openhab.org/docs/configuration/rules-dsl.html#time-based-triggers
points to https://www.quartz-scheduler.org/documentation/quartz-2.2.2/tutorials/tutorial-lesson-06.html as the reference for the cron syntax.

• Month: quartz's docs say: month is from 0-11 (0 = January?) but based on experiment with openhab, it appears that this should be 1-12. This cron job runs now (March) * * * * 3 * which means 3 = March, and therefore 1 = january.
• Last day of week: Quarts docs say L = SAT. In openhab's code it seems that L = SUN, although I haven't tested this one yet.

Changing any of this would break existing code, so perhaps the docs need to be updated instead?

Hm,

We have different rule engines allowing to use cron, so we should also check if this affects other docs too.

Since everything is quartz based we should then link to quartz as the basic sourc and add a list of "Exceptions".
