Unix time (POSIX time) is a system for describing points in time, defined as the number of seconds elapsed since midnight Coordinated Universal Time (UTC) of January 1, 1970, not counting leap seconds.

At 11:31:30pm UTC on Feb 13, 2009, Unix time will reach 1,234,567,890. You can verify this as follows:
$ date -d@1234567890
Sample output:

Fri Feb 13 17:31:30 CST 2009

This will be happening on Sat Feb 14th early in the morning in New Delhi, India (IST local time):
$ date -d@1234567890
