run on custom clocks not wall clocks

Does csp support using custom clocks instead of wall clocks? I haven't found it. But if it does, I think it would be very helpful. Here's a specific use case that could be very common.

Say we are using csp to analyze traffic data of an online streaming event that only goes live 2:00pm to 4:00pm every day. And our goal is to read back several days of traffic data + using live data to generate signals to help increase live traffic. Currently, I think we can only just do csp.run for the full wall clock of past, for example, 5 days to calculate features. Most of the ticks will be NaN since there's no data. If we could define 2:00pm~4:00pm to be a day and csp engine only runs on these time range, that would save lots of trouble and speed up calculations as well. I would love to hear about your thoughts on this.

Thats an interesting problem. I think the best you can do at this point is to csp.filter your input source right at the start so it only ticks into your graph between the times that you want.
You would still pay the overhead of reading in all the data, but it will avoid any computation overhead outside of those hours
