I want to be able to set a time for Sonar to record, and then stop.
 
Anyone, anyone, Bueller, Bueller,...

Create a 24 hour long project and set punch in points? 
 

You can use or make a software that sends a timed keystroke "R" to SONAR and then after a while a timed "[Space]". For example with Visual Basic.
Or you can record 2 days and then cut out what you wanted to record. SONAR has no problem to record 2 days.
 

Scripting would be my solution. Something like Autohotkey.

Software products like "Autohotkey" are not able to make a absolute time (as 9:00) to record and stop (as 9:16). They can only set a delay in the range of seconds between record and stop. But never absolute time.
If recording must be set to an absolute time as 9:00 then scripting is in my opinion only possible with VB scripts (or Visual Basic). Because the script must have access to the windows timer.

Im glad you said it and not me. because I was thinking the same thing 

If it's only a stereo recording most wave editors have timers settings. 
Also screen capture programs do this. I use Debut Video Capture to record webinars. You can then export just the Audio, just did this last night.

I will laugh about this all day.
