Unix Tip #4493- June 30, 2023
YET ANOTHER COUNTDOWN
The unix time() value will rollover
to 10 digits for the first time in
modern computer history starting
Saturday Sept 8th,2001. The
timestamp will be 10 digits long,
and not 9.
Here's a short Perl script to
compute the time left:
#!/usr/bin/perl -w
use strict;
my $now=time();
my $target='1000000000';
my
($sec,$min,$hrs,$dom,$mon,$year,$wday,$yday,$isdst)=localtime($target
- $now);
my $now_string=localtime(time());
my $target_string=localtime($target);
my $message=qq{today is $now_string\n$mon months $dom days $hrs
hours $min minutes $sec seconds left till U1e9
($target_string)\n};
print $message;
