Year 2038 Bug
Computer programs,
softwares and systems that uses 32 bit integer to represent UNIX Time will fail after 19th, Jan, 2038
at 3:14:07.
What ?
Unix Time
is another way
of telling time, mostly for computer’s understanding. Each instances are defined
as number of seconds elapsed after
1970-01-01 00:00:00
.
Eg
:
UNIX Time for
31st Aug 2012 18:59:09 = 1346439549
On 19th, Jan,
2038 at 3:14:07, the 32 bit signed integer will reach its limit. After that,
bit will overflow the 32-bit counter and reset the time to 1st Jan,
1901.
Attention to Mysql Users
Mysql 5 is a 32 bit
database, it has a function UNIX_TIMESTAMP()
which returns seconds since
The end time would be different for each region based on their time zone.

. This function will return only 0 after 19th
Jan, 2038 03:14:07 GMT.The end time would be different for each region based on their time zone.
