Last ditch effort for #69, removes quotes and trailing Z's manually and also removes nanoseconds since they're useless.
I think this means UTC-08:00, but this just strips it since time handling is pretty naïve already.
now actually removes the already deleted user from the expiry list.
Also means times are directly parsed when pulling data from jf/emby, which was *painful* to get working (something broke the whole program and it took me an hour to figure out it was this lol). Time parsing should be a lot stabler too.
