QUESTION
The way the Linux kernel handle time is somewhat complicated as it uses different source of time, and regularly resynchronize everything. There are command-line tools (like hwclock
) to query the RTC time explicitely. However I would like to do it programmatically, inside a C or C++ program. If Linux provides command-line tools, I assume that there is a way to do this programmatically, but so far I haven't been able to find the right function, and how to use it.
So my questions are:
...ANSWER
Answered 2018-Jul-27 at 05:39Use time(time_t*) or clock_gettime(clockid_t,struct timespec *) if you wish for more precision, from the time.h header for the RTC time.
there is an article describing how to get query NTP time ( which was a google search away ).

QUESTION
I read the documentation of std::time
and discovered that there are 3 types of time available:
I need the implementation which is closest to RTC with almost no clock drift. I need to use the times across machines in a distributed system.
I thought of going with Instant
, but then I also read this:
Note, however, that instants are not guaranteed to be steady. In other words, each tick of the underlying clock may not be the same length (e.g. some seconds may be longer than others).
Which one is the best fit for a distributed environment?
...ANSWER
Answered 2018-Jun-21 at 19:13Of the three, Instant
seems like it would give you the closest approximation of a RTC, at least within the context of the system.
In a distributed sense, you'd probably want to have only one instance across one machine and query it on the others to get relative time, that way you are guaranteed at least consistency in event times.
After a cursory glance, I was unable to find an out of the box solution if you want accurate time.

I have two mysql queries that I'd like to combine. I'm shame-posting here as I've tried many combinations to make it work but can't figure it out. I guess I've hit a ceiling in my query writing abilities. :(

I have been trying to create a clock in and out the system, for the small business that I work for.
At the moment I am having trouble getting it to talk to the MySQL server. I am probably doing something really silly wrong.
