Job schedule is not accepting crontab formatting that includes / (step values)

[kouroshshafi]

In admin panel job schedule is not accepting jobs with / in them (step values); say a job of scanning at every other hour: 0 */2 * * *

The / is not getting saved at all in the admin webui

I think this is an issue with the way cron formatting is validated.
