"timer" limit?

[Bipolar_Games]

What happens to the "timer" variable (Timer count in 1/1000 seconds since start of frame) when it reaches its limit of 2147483647 after approximately 24 days of an application running?

It would wrap according to the C/C++ standard.
2147483647 is the maximum of a signed integer, thereby it would wrap to -2147483648 and count up from there.

It may be internally stored as a larger or even unsigned type, however, so internal timer-related functions may still work fine.
