Cron Expressions

When updating from v2018.1.x or v2018.2.x to either v2018.4.x or v2019.x, the use of invalid cron expressions in your schedules causes them to stop working. See below examples of incorrect cron syntax, the corrected expression, and its description.

Incorrect Syntax	Corrected Syntax	Description
0 45/60 09-16 ? * MON-FRI *	0 45 09-16 ? * MON-FRI *	At 45 minutes past the hour, between 09:00 AM and 04:59 PM, Monday through Friday.
0 30/60 09-15 ? * MON-FRI *	0 30 09-15 ? * MON-FRI *	At 30 minutes past the hour, between 09:00 AM and 03:59 PM, Monday through Friday.
0 0/120 22-03 ? * MON-SAT *	0 0 22-03/2 ? * MON-SAT *	Every 2 hours, between 10:00 PM and 03:59 AM, Monday through Saturday.

Please note that this issue is only encountered for schedules defined specifically with cron expressions, using the Advanced option.
