Como interpreto a saída do w32tm?
08:38:08 d:+00.0311860s o:+00.2011040s
-
08:38:08
é a hora local -
d:+00.0311860s
é o atraso interno (diferença de tempo entre o pacote udp recebido e o pacote udp enviado no lado do servidor -
o:+00.2011040s
é o deslocamento real entre a hora local e a hora do servidor
Isso ainda deixa d: ... essa latência de ping?
Do I need to add those seconds with o: to get the final time of the remote time server?
O o:
é o deslocamento real, portanto você não precisa adicionar d:
para obter a hora final.
The console application w32tm.exe allows monitoring of the offset of the local time to the time of an internet time server.
The easiest way to do this is from a console window with the following set of parameters:
w32tm /stripchart /computer:time.windows.com /period:120
As a result, the system time and its offset to the time server are dumped to the console every 120 seconds:
Tracking time.windows.com [65.55.21.14.123]
08:38:57 d:+00.0417301s o:+00.1024506s [ * ]
Each line consists of the local time (08:38:57), an internal delay (time difference between the udp package received and udp package sent on the server side, i.e., d:+00.0419394s), the actual offset between the local time and the server time (o:+00.1024506s) and a very basic stripchart of the offset.
