Hi everyone,
I'm writing an handler for a proprietary kind of GPS clock, using RS232
signals and the SHM driver.
The NTP documentation describes the structure of the memory segment, and
says that :
"[...] (clockTimeStampSec, clockTimeStampUSec,
receiveTimeStampSec, receiveTimeStampUSec,
leap, precision) are passed to ntp
[...]"
What value(s) should I set, while my GPS clock only sends me the
following values :
- Day
- Month
- Year
- Hour (local time)
- Minutes
- Seconds
Once every minute. I use them to build a UNIX time_t. Should it be
stored in clockTimeStampSec or receiveTimeStampSec ?
What about leap & precision ?
Thanks in advance.
Jerome.
