我想计算 windows 上低于时间戳的时间差异。
tt1= 2013/08/16 23:59:59:785
tt2 = 2013/08/16 23:59:59:753
和输出应该是:000826.288000
我试过下面的代码,但输出为 16799588.000000 。
但输出应该像 000826.288000 。请帮我获得正确的时间戳 000826.288000。
use DateTime::Format::Strptime;
my $dp = DateTime::Format::Strptime->new(
pattern => '%Y/%m/%d %H:%M:%S:%3N'
);
# Create two DateTime objects
my $tt1 = $dp->parse_datetime('2013/08/16 23:59:59:753');
my $tt2 = $dp->parse_datetime('2013/08/16 23:59:59:785');
# The difference is a DateTime::Duration object
my $diff1 = $tt2 - $tt1;
#print " t1 and t2 are : $diff $tt1 and $tt2 \n";
my $diff = sprintf "%013.6f", $tt2 - $tt1;
