ping is a very useful and common command to test the link to another site.
It is frequently used to test whether the network is working or not.
But there is no time stamp in the output when using ping on windows, which made it hard to debug a short network break.
To solve this issue without install a 3rd party tool, powershell could be used:
Test-Connection -count 9999999 -delay 2 www.bing.com | select {Get-Date} , Address , IPv4Address ,ResponseTime
By select the objects of output, adding {Get-Date} info to the output, the timestamp could be output.
Update 2022-12-28
Another command also works
ping.exe -t www.bing.com|Foreach{"{0} - {1}" -f (Get-Date),$_}
