=head1 NAME
ts - timestamp input
=head1 SYNOPSIS
ts [-r] [-i] [format]
=head1 DESCRIPTION
ts adds a timestamp to the beginning of each line of input.
The optional format parameter controls how the timestamp is formatted,
as used by L<strftime(3)>. The default format is "%b %d %H:%M:%S". In
addition to the regular strftime conversion specifications, "%.S" and "%.s"
are like "%S" and "%s", but provide subsecond resolution
(ie, "30.00001" and "1301682593.00001").
If the -r switch is passed, it instead converts existing timestamps in
the input to relative times, such as "15m5s ago". Many common timestamp
formats are supported. Note that the Time::Duration and Date::Parse perl
modules are required for this mode to work. Currently, converting localized
dates is not supported.
If both -r and a format is passed, the existing timestamps are
converted to the specified format.
If the -i switch is passed, ts timestamps incrementally instead. Every
timestamp will be the time elapsed since the last timestamp.
The default format changes to "%H:%M:%S", and "%.S" and "%.s" can be used
as well.
=head1 ENVIRONMENT
The standard TZ environment variable controls what time zone dates
are assumed to be in, if a timezone is not specified as part of the date.
