NAME ^

Log::Stamper - generate the formatted stamp for logging

SYNOPSIS ^

    use Log::Stamper;

    my $stamp = Log::Stamper->new("yyyy-MM-dd");

    # Simple time, resolution in seconds
    my $time = time();
    print $stamp->format($time); # 2013-01-13

    # if you use milliseconds
    use Time::HiRes;
    my $stamp = Log::Stamper->new("HH:mm:ss,SSS");
    my ($secs, $msecs) = Time::HiRes::gettimeofday();
    print $stamp->format($secs, $msecs); # => "17:02:39,959"

Typically, you would initialize the stamper once and then reuse it over and over again to display all kinds of time values.

DESCRIPTION ^

Log::Stamper is a formatter which allows dates to be formatted according to the log4j spec on

    http://download.oracle.com/javase/1.4.2/docs/api/java/text/SimpleDateFormat.html

which allows the following placeholders to be recognized and processed:
