Time sync system clock R&S RTB2004

<< < (5/9) > >>

Either way, if you have an internet connection you can use oodles of NTP servers. So it is not like having an NTP server on a router is going to provide more features. After all, the NTP server on a router will need to get the time from somewhere as it likely doesn't have an accurate internal RTC. For standalone use you might want to venture into GPS enabled NTP servers but it appears there are also phone apps that can turn your phone into an NTP server.

I totally sympathize with the desire of the OP to have the right time set on instruments in order to have files and screenprints carry the right time and date. If possible, a time server function that automatically updates, with time zone support and all, would be ideal. Some instruments have this (the degree to which this actually works varies ;-) and others do not have it.

But to put this into perspective: I have several recent and not-always-so-cheap instruments in my lab that have no time and date setting at all!! Not even manual...  (Not going to do naming and shaming now). That is hugely inconvenient. The files created on a USB stick etc. carry time stamps like “30 Dec 1999 at 23:00”. Oef!

Now there's a project for you to check which instruments you have that keep the most accurate time.
1 month should show some variance......

At the risk of derailing this nice R&S thread, I have to say that the Siglent SDG1000X arbitrary wave generator (and probably its siblings) gets a special mention for waking up at each power-on thinking it is midnight, January 1, 1970.  :-//
   I actually modified pdenisowski's Python script to set the time and date of the SDG, but there is really not much point since the data is volatile and resets on every power cycle. In case anyone is interested, though, that modified script is attached.

That's a Unix-style timestamp that's set to all zeros.  "Unix time" is the number of seconds since midnight, January 1, 1970 :)
