Like "time", but "today" does not wrap to tomorrow. If suites' begin time is past the time given for the "today" command the node is free to run (as far as the time dependency is concern.)
today 3:00 # today at 3:00 today 10:00 20:00 01:00 # every hour from 10am to 8pm
This is useful when you have early morning time-dependency, but you want repeat the suite in the afternoon. Otherwise the node would wait till the next morning to run.
