Hi, I think I may have discovered a bug in DateTime::Format::Strptime. I am
using version 1.5000.
It seems to me that 4 digit years are parsed incorrectly, when you specify %y
in the format string. My interpretation of the docs is that %y should be able
to handle both 2 digit and 4 digit years.
Here is my test code:
#!/usr/bin/perl -w
use DateTime::Format::Strptime;
my $Strp = new DateTime::Format::Strptime(
pattern => '%d %m %y',
);
my $in;
$in = '1 3 2011';
my $dt;
$dt = $Strp->parse_datetime($in);
my $epoch;
$epoch = $dt->epoch;
print gmtime($epoch)."\n";
# prints Sun Mar 1 00:00:00 2020
# but I expected Tue Mar 1 00:00:00 2011
From the docs:
# From man DateTime::Format::Strptime
# %y
#
# The year within century (0-99). When a century is not otherwise
# specified, values in the range 69-99 refer to years in the
# twentieth century (1969-1999); values in the range 00-68 refer to
# years in the twenty-first century (2000-2068).
#
# %Y
#
# The year, including century (for example, 1991).
Let me know if I am misunderstanding something.
Thanks,
Rohan.
