Hi everyone
In my application I require a continuous timestamp appended to my scope data. I planned to read out the RTC value and append this to the JSON packets in my Web App (maybe at least as sort of a header information).
In this respect, my question is how to read out the system time and where do I find it?
However, I noticed when updating files via SSH that no file property date is updated correctly.
The initial date remains January 1st, 1980 01:00:00
In this case, I will also have to set the RTC.
Best regards
Georg B.

Re: read out System Timestamp
I hate to break this to you, but the Red Pitaya doesn't have an RTC. That's why it always boots with the time set to unix epoch (1/1/1970 0:00 UTC).
It may be possible to set the system time from an NTP server in the startscripts, provided your RP has internet access.
Once the system time is set, you can use the usual APIs for time, like gettimeofday()

Hi Nils
Thank you for your quick reply! I was a little afraid in advance to hear this.
Will the setting of the system time work also with the standard APIs?
Say ... settimeofday()
I don't know what the time.h library does in the background, but I guess the linux OS provides this anyway.
