STM32F413VH RTC using LSI

We are using STM32F413VH in one of our projects. We were planning to use the RTC peripheral with LSI as clock source to get timestamps and check weather the tasks are running periodically. We are planning to use RTC as it is independent of the system clock.

My question is how stable & accurate is the LSI? Can we use it to accurately measure time?


Thanks in advance.
