Hi Experts,
I am doing NW BPM to collect the messages during the day and end the BPM at 10PM every day, I have done BPM design to collect the messages using this blog Collect Pattern in NW BPM - Part I
I want to use the expression in Timer Configuration

Can you help me with the expression, i wanted to use expression like get the milliseconds between 10PM and the current time (BPM start time)
For example if the BPM starts at 10AM in the morning, i need to get the milliseconds between 10PM and 10AM and pass the milliseconds in the expression.
Regards,
Santhi.
