This code provides test to check if time on target machine is properly
read via ntp_gettime syscall.
---
Changes for v2:
- Check time before and after calling ntp_gettime{x} to avoid situation
when seconds rollover between call to ntp_gettime and wrapper providing
current time.

The correct indentation is:
do

}
while (...)
The test looks ok.
