NAME

       ts - timestamp input

SYNOPSIS

       ts [-r] [-i | -s] [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" and "%.T" are like "%S" and "%s" and "%T", but
       provide subsecond resolution (ie, "30.00001" and "1301682593.00001" and "1:15:30.00001").

       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 or -s switch is passed, ts timestamps incrementally instead. In case of -i,
       every timestamp will be the time elapsed since the last timestamp. In case of -s, the time
       elapsed since start of the program is used.  The default format changes to "%H:%M:%S", and
       "%.S" and "%.s" can be used as well.

       The -m switch makes the system's monotonic clock be used.

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.
