Release : 15.9.1


Clarity does not support full Unix crontab syntax, just a selective set. A workaround is as below.

Currently Cron parser in Clarity does not support "-" or "/" as Cron operators. Clarity supports "," as a separator for days of week. Please change your schedule definition from "1-5" to "1,2,3,4,5" in order to schedule the job.

0 2 * * 1-5
should be
0 2 * * 1,2,3,4,5
