15 cfa37a7b 2004-04-10 devnull .SH DESCRIPTION
16 cfa37a7b 2004-04-10 devnull Both
17 cfa37a7b 2004-04-10 devnull .I time
18 cfa37a7b 2004-04-10 devnull and
19 cfa37a7b 2004-04-10 devnull .I nsec
20 cfa37a7b 2004-04-10 devnull return the time since the epoch 00:00:00 GMT, Jan. 1, 1970.
21 cfa37a7b 2004-04-10 devnull The return value of the former is in seconds and the latter in nanoseconds.
