SYNOPSIS

       tai64n

DESCRIPTION

       tai64n reads lines from stdin. For each line, it writes

       1      an @,

       2.     a precise timestamp,

       3.     a space, and

       4.     a copy of the input line

       to  stdout.  The  timestamp  indicates  the moment that tai64n read the
       first character of the line.

       tai64n does not allocate any memory after it starts.

TIMESTAMPS

       Timestamps used by tai64n are 12-byte TAI64N labels in external  TAI64N
       format,  printed  as  24  lowercase hexadecimal characters. You can use
       tai64nlocal(8) to convert the timestamps to a human-readable format.

       For example,  the  timestamp  4000000037c219bf2ef02e94  refers  to  the
       nanosecond  beginning  exactly  935467455.787492500  seconds  after the
       beginning of 1970 TAI; 37c219bf hexadecimal is 935467455, and  2ef02e94
       hexadecimal is 787492500.

       The  current  implementation  of tai64n relies on the UNIX gettimeofday
       library routine to return the current time as the number of TAI seconds
       since  1970-01-01 00:00:10 TAI. Beware that most gettimeofday implemen-
       tations are not Y2038-compliant. Furthermore, most clocks are  not  set
       accurately.

EXIT CODES

       tai64n exits 0 when it sees end of input. It exits 111 without an error
       message if it has trouble reading stdin or writing stdout.
