I am running into a function run timeout error after 5 minutes for my schedules.  The Functions - Limits documents states it should be 15 minutes:  Functions - Limits | Online Help - Zoho CRM. What should it actually be?

Due to the 5 minute timeout, I'm unable to get through more than around 1200 Account records using page iteration, and this is not a long function at only around 26 lines. I feel strongly Zoho needs to greatly improve upon its current capabilities in the ability to process larger quantity of records in functions. Any medium sized business is going to have a much higher quantity of records it needs to process. Schedules is practically useless to me if I can only get through 1200 records. 

Including a screenshot of the timeout error.
