Question
The 2038 bug
My curiosity recently brought me to analyse what is the exact nature of the 2038 date problem.
Well as you all probably know, it comes from the limitation in the C standard library type 'time_t' which is usually defined as a 32 bits signed integer.
The time_t type is defined by the C standard to contain "the number of seconds elapsed since January 1, 1970, 00:00:00". The C documentation says it can contain dates up to January 18, 2038, 19:14:07.
But when I calculate the number of seconds a 32 bits signed integer can contain, I come to the number 2147483647, which is 24855 days, 3 hours, 14 minutes and 7 seconds. Adding this value to January 1, 1970, 00:00:00 gives the following date: January 19, 2038, 03:14:07
So how can you explain the difference between the C documentation date and the calculated date ?
