TIMESTAMP(1)TIMESTAMP(1)NAMEtimestamp - log event times
SYNOPSIStimestamp [ 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 tim‐
ings to change, and that the timestamps are only as accurate as the
times reported by /dev/time.
