Two Questions

[MaDhAt2r]

Hello All!

I have been using notmuch/emacs for about two years now. I of course
love the setup, but there have always been two main issues I have yet to
find a solution for. I am hoping someone on here has found some answers.

1. How to change the time/date to use 12h format in all displays.

2. How to handle mailto:// hyperlinks and force the use of emacs/notmuch

I am running on ArchLinux (4.1.15-1-lts kenel), Emacs 24.5.1, notmuch 0.21

Thanks for your help!
