Time::Piece strptime has trouble with %X

Question

I'm trying to parse the following data using Time::Piece->strptime() in perl v5.26:

my $str = "Mon Feb 21 02:54:49 IST 2022";
my $time_zone = substr($str, 20, 3);
my $date_time = Time::Piece->strptime($str, "%a %b %e %X $time_zone %Y");
print "Todays date/time is : $date_time";

But, when I execute the above code snippet, I get the following error:

Error parsing time at /usr/local/lib64/perl5/Time/Piece.pm line 598.

I'm not sure what is it that I'm missing out, any help will be really helpful.
