.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Fn rtime
|
||
|
|
function
|
||
|
|
consults the Internet Time Server at the address pointed to by
|
||
|
|
.Fa addrp
|
||
|
|
and returns the remote time in the
|
||
|
|
.Vt timeval
|
||
|
|
struct pointed to by
|
||
|
|
.Fa timep .
|
||
|
|
Normally, the
|
||
|
|
.Tn UDP
|
||
|
|
protocol is used when consulting the Time Server.
|
||
|
|
The
|
||
|
|
.Fa timeout
|
||
|
|
argument specifies how long the
|
||
|
|
routine should wait before giving
|
||
|
|
up when waiting for a reply.
|
||
|
|
If
|
||
|
|
.Fa timeout
|
||
|
|
is specified as
|
||
|
|
.Dv NULL ,
|
||
|
|
however, the routine will instead use
|
||
|
|
.Tn TCP
|
||
|
|
and block until a reply is received from the time server.
