How measure direnv load time?

[kaddkaka]

When I add something to my nix environment which I load with direnv, it can take minutes or hours to update my environment. Is there some way to measure/profile this load time?

I tried time direnv reload and date ; direnv reload ; date but the problem is that the direnv command completes immediately.

Followup question: When the update time to the environment takes >1 hour, is it possible to it in the background but still get the most of the environment loaded?

I added date to the first and last line of my .envrc file.

This did not work, I ended up doing PROMPT_COMMAND+=('date')
