.SH "Description" 
.PP 
Warning: V1 compatibility only. For new programs, please see \fBgethrtime(3)\fP, \fBclock_gethrtime(3)\fP. 
\fBrt_get_time\fP returns the time in clock ticks since the system 
bootup. This 
time is never reset or adjusted.  For some horrible reason, 
\fBhrtime\fR has a differrent meaning when the V1  compat 
config option is selected. This is a BUG! 
.PP 
The \fBRT_TIME_END\fR symbol represents the maximum possible value that \fBrt_get_time()\fP could possibly return.  This value will be never 
reached during the execution of the system, and can be used to designate the infinitely distant moment in time. 
.SH "Notes" 
.PP 
"Clock ticks" are PC 8254 timer ticks (1/1193180s). This function is part of the RTLinux v1 compatability API. Use in new applications is not encouraged.
