how does the internal RC clock deviation of STM32L071VBT6 change with years?

[xxm]

I have a project that uses the internal RC clock used by the STM32L071VBT6 as the system clock. During the test, it was found that some of the other communication ports were not working properly under the low temperature of -40 degrees. The latter analysis confirmed that the RC clock deviation was high at low temperatures, then I After testing the prototype working at -40 degrees for several years, how does the internal RC clock error change, and how much is the change?
