[etherlab-users] master application time seting

[Bilko AS, Oguz Dilmac]

Hi,

Can we just feed rt_get_real_time_ns() to the 
ecrt_master_application_time directly?
like: ecrt_master_application_time(master, rt_get_real_time_ns())

In the DC RTAI example, the time is first read byrt_get_real_time_ns() 
to a tv variable.
Then at each cycle, tv variable is incremented as the expected cycle period.
Then it is given to ecrt_master_application_time(master, 
EC_TIMEVAL2NANO(tv)) at each cycle.

Why is this approache is used? It seems problematic due to the jitter of 
the periodic task period.

Best regards,
Oguz.
