NAME

6       ts - timestamp input
7

SYNOPSIS

9       ts [-r] [-i | -s] [format]
10

DESCRIPTION

12       ts adds a timestamp to the beginning of each line of input.
13
14       The optional format parameter controls how the timestamp is formatted,
15       as used by strftime(3). The default format is "%b %d %H:%M:%S". In
16       addition to the regular strftime conversion specifications, "%.S" and
17       "%.s" are like "%S" and "%s", but provide subsecond resolution (ie,
18       "30.00001" and "1301682593.00001").
19
20       If the -r switch is passed, it instead converts existing timestamps in
21       the input to relative times, such as "15m5s ago". Many common timestamp
22       formats are supported. Note that the Time::Duration and Date::Parse
23       perl modules are required for this mode to work. Currently, converting
24       localized dates is not supported.
25
26       If both -r and a format is passed, the existing timestamps are
27       converted to the specified format.
28
29       If the -i or -s switch is passed, ts timestamps incrementally instead.
30       In case of -i, every timestamp will be the time elapsed since the last
31       timestamp. In case of -s, the time elapsed since start of the program
32       is used.  The default format changes to "%H:%M:%S", and "%.S" and "%.s"
33       can be used as well.
34

ENVIRONMENT

36       The standard TZ environment variable controls what time zone dates are
37       assumed to be in, if a timezone is not specified as part of the date.
