Hi
So welcome in guys, let's start off and lets hope that we grow into one
really good interest group and do some cool stuff on the way.
So I though maybe we can start off by discussing the Y2038 issue that we
face. In the 90s the planet went crazy over the y2k problem in handling
dates but was corrected efficiently and in time to avoid a global
meltdown of IT infrastructure. But today we know that we are looking at
something bigger and more diabolic coming our way. Nick named Y2038
problem is the issue computers and embeded systems are going to face in
the year 2038 due to the current date and time representation system we
use.
Currently computers and embedded systems use a 32 bit integer to store
and process date and time in UTC. The issue is that on exactly 2038 -
01 - 19 at 03:14:08 all the bits will set to 1s and then re set to 0s
as that would be the maximum value that can be stored in 32 bits (Unix
time format).
The date and time will effectively get reset to 1901-12-13 20:45:52.
Technical reason : he furthest time that can be represented in the Unix
time format is 03:14:07 on Tuesday, 19 January 2038 (2147483647 seconds
after January 1st,
1970).^<https://en.wikipedia.org/wiki/Year_2038_problem#cite_note-spinellis-2>
Times beyond this moment will "wrap around" and be stored internally as
a negative number, which these systems will interpret as a date in
December 13, 1901 rather than January 19, 2038.
The worst part about this seems to be that there is no possible easy fix
that can be applied universally. the greatest hit will be embedded that
include devices that are critical to our daily life.
Cheers
