I'm trying to get the date when each port/pkg was istalled or upgraded. Actually I'm using the command
or (in my case)
where
# pkg query '%t' <pkg-name>
or (in my case)
# pkg query '%t' `pkg info -q -O <port-name>`
where
<port-name>
is the common form used by portmaster and portupgrade 'category_name/port_name' (for example the package tmux correspond to port sysutils/tmux). As far as I know the date returned is not the first installation date as I guessed at first sight, it change when port is upgraded and this is what I'm looking for. Anyone know if what I said is right?
