Ok I can't say that it will work for your camera. However I just ran this command for testing the time on my AD410 and I get the result back as expected. So it might work with your ASH43.
/cgi-bin/global.cgi?action=getCurrentTime
That command will get the current time info
/cgi-bin/global.cgi?action=setCurrentTime&time=2023-9-20%01:22:32
Is for setting the date and time. Please note that the setup is Year, month, day and hour, min, second
Don't forgot it will be sent with http and the : // with the camera current IP address. If you setup right format you should get an ok if you get an error the caps and small leters have to be just as I posted it or it will fail.
