When i was trying to schedule and start my runtime, i had a peculiar issue. I followed the instruction specified here at

https://pdn.pega.com/node/1481006/book_pdf

If we are running it once a day all works well. When i try to add another entry for a same day it is not triggering. I had an entry like

"Wednesday": {
"Enabled": true,
"StartTime": "08:00",
"DurationMinutes": 120
},
"Wednesday": {
"Enabled": true,
"StartTime": "20:00",
"DurationMinutes": 120
},

Basically i was trying to start it once in the morning and once at the end of day. What is the right way of setting time for more than once a day?
