last update time of hardware clock (Windows and Linux) with the Server

thanos1983 has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks,

I am looking for a function that can provide me the last update time of the hardware clock on Windows/Linux OS through Perl.

Update: The last update time that the OS was synchronized with a time server.

I have been looking over the web and I can not find something similar. I can find modules to play around with the hardware clock such as Test::MockTime or Time::Mock but they are not suitable from my request.

I want a function that will reply back with the epoc seconds since the last update time. For example since last update time of hardware clock was 5.7 sec.

Thank you in advance for your time and effort.

I am looking for a function that can provide me the last update time of the hardware clock ... What do you mean by the "last update time"? Do you mean: the last time it was manually adjusted? the last time it was synchronised with a time server? the last time it was incremented by the hardware interrupt?

Hello BrowserUk, You are absolutely right. This is very important details that I did not mention it. I am looking for the last time it was synchronized with a time from the server.

I am looking for the last time it was synchronized with a time from the server. On windows, you can parse the output of: `w32tm /query /status`. It is the 7th line of 9. The info is probably in the registry somewhere, but a quick search of ms.com didn't turn up the relevant key.

`ntpq -p` on Linux might help... See NTP: ntpq output explained and NTP Debugging Techniques. Update: added link. Regards, Karl ŤThe Crux of the Biscuit is the Apostropheť	[reply] [d/l]
