Hi,
I wanted to come back and say this has been resolved for me.
I emailed a developer this question and they replied saying the following:
"You can set max_execution_time to 0(zero) so it will be like unlimited. Using this value you can try first and if everything works fine. you can find the best value suitable for your shop."
I contacted my hosting provider with the message above. They replied saying, they have temporarily disabled the max_execution_time directive on my account.
I hope this helps everyone seeking this answer.
