Inferno's TIMESTAMP(1 )

NAME

timestamp - log event times

SYNOPSIS

timestamp [ tag ]

DESCRIPTION

Timestamp reads lines from its standard input and writes them to its standard output, prefixing each line with the time that it was written, in decimal milliseconds since timestamp was started. If tag is given, it is written along with the time stamp on each line, to enable tagging if several writers are each writing to the same log file.

The first line written gives the time that timestamp was started, in milliseconds since the epoch. Note that logging events can cause timings to change, and that the timestamps are only as accurate as the times reported by /dev/time.
