Thanks for an interesting use case. */5 is just a short hand for 0-60/5, so I guess the general case that needs to be considered here is how to use hash in "(s-e)/d" construct.
What's the good syntax here? H(s-e)/d? H(*)/d vs H/d? 2012/5/23 Maven User <maven.2.u...@gmail.com>: > I just saw this and am kinda intrigued... > > Currently, we have 30 - 40 jobs all configured as */5 * * * * (so every 5 > min) for their polling interval. > > But then I see this "H" thing.... > > "To allow periodically scheduled tasks to produce even load on the system, > the 'H' token can be used.
