Overflow in time.localtime()

[MrRobot]

So I had a bug in my code that produced an invalid timestamp.

I solved the bug but thought it was strange that there's a max int for locatime()

What is the maximum value you can pass to localtime() ?

Running on stable build 1.12 on Pyboard D SF6W

Bug below:

time.localtime(2366758325)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OverflowError: overflow converting long int to machine word
