When I was registering, I use my default randomizer password generator to generate a password 20 characters in length, however the site took this as over 20 because it used certain special characters in it. I'm just wondering, why max the password at 20? I'd say 30 would be more reasonable a number for a max but, eh anyway. Luckily I was able to randomly generate another and that one worked.

The time zone selection is a mess however, I ended up just selecting a random one that said my time because they are all scattered about, no idea which one is the right one. I suggest instead of using states or city names, use the unmistakable method UTC +1 +2 or whatever. With the option that it also shows "current time" on it like it does with yours, but it'll be far less options and be more broad so users don't have to try and guess which specific one.

Thank you for your feedback!

As for the PW length, there is no particular reason why it was set to 20. I just figured it is enough for a random password. However if one likes to have a peculiar sentence as password for example (which is quite secure) it is not enough. I set the PW length to 30 now.

As for the Timezones:
I think the list is the best and simplest approach, also how the timezone is stored in the database. It's a bit overwhelming at first. But unless you do travel around a lot it is a setting that must be only done once and never again. Also it is ordered by continent which should help.

UPDATE:
I have added timezone abbreviations to each city now, hope this helps. :)
