Just to note contemplation of cron-like real time scheduling in Cylc can get quite mind-bending when you consider things like: we could have parts of a cycling Cylc suite tied to a real time schedule while other parts (even with the same cycle points, potentially) are not tied; and note that ICP = now
and ICP = next(...)
choose ICP relative to real time "now" BUT tasks in the first cycle point will still trigger without regard for the clock unless entirely optional clock-triggers are attached to them.
Issue discussed in this Discourse thread: https://cylc.discourse.group/t/cylc-question-on-wall-clock-synchronization/58
For example, in order to start a crontab job to run every 5 minutes starting from the earliest 5, 10, 15, etc minutes past the hour, the crontab syntax is just:
In Cylc, user has to do:
It is fair to say that Cylc needs to do more than Crontab, but we should at least try to find a way to simplify the
initial cycle point = next(...)
syntax.
