NAME
       ts - timestamp input

SYNOPSIS
       ts [-r] [format]

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 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,A converting localized dates is not supported.

       If both -r and a format is passed, the existing timestamps are converted to the specified format.

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.
