How to monitor latest packages?

Hi,

I used to compile all of my ports from the git repository using poudriere. 
Recently I started to use poudriere's pre-fetching functionality (due to resource hog rust).
I am using pkg+http://pkg.FreeBSD.org/\${ABI}/latest <pkg+http://pkg.FreeBSD.org/%5C$%7BABI%7D/latest> and my current ABI is FreeBSD:14:amd64.

I am trying to monitor the dates of pkg compilation runs by http://pkg.freebsd.org/FreeBSD:14:amd64/latest/
Is that the correct way?

If so, how can I find out when e.g. rust has been compiled the last time, because http://pkg.freebsd.org/FreeBSD:14:amd64/latest/All/ seems to be forbidden to watch ;-)

If not, what would be an alternative?

Thanks in advance and regards,
Michael
