Extract grace period information

[Kociszev]

I need to extract password expiration date for all the account I have on a TRU64 server.

I can find this information with dxaccounts application.

But it is very boring to do when you have almost 300 user accounts on a server.

I have tested to use "passwd -qa" command line but it seems the date obtained with adding last change date + delay is not corresponding with the grace period given by dxaccounts application.

Can you have a most effective solution for me ?
