[CLIENT] Timezone error (adding +30 minutes) for anything to do time related in the client. (OCE)

The bug occurs if you have your timezone on x:30, so any iteration that isn't a full hour. (In my case I'm on utc 9:30 ((in Oceania))

Changing my timezone to either 9:00 or 10:00 fixes the issue and it doesn't have the added 30 minutes, from my limited knowledge of timezones in games today they're quite difficult so I don't mind, it doesn't change anything in terms of gameplay but it's a bit confusing if I dodge or miss champion select due to any reason and try to rejoin the queue it says 35:00 minutes till I can join again.

Steps to reproduce:

1. Change timezone to x:30 (where x is any number) (Link to an example of the +30 with timezone evidence) (apologies for the Ekko smirking at you)
2. Restart the client
3. Observe +30 minutes onto any timer in any queue. (Link to an example of the normal queue with a x:00 timezone.) (apologies for the Ekko smirking at you)

Frequency: 10/10 attempts in both scenarios.

Scenario 1: Timezone: UTC 9:30. Every time related text on the client has + 30 minutes added to it. Scenario 2: Timezone: UTC 10:00. Every time related text on the client does not have + 30 minute added to it and functions normally.

tl;dr: Timezone on x:30 (where x is any number) results in + 30 minutes added to every queue and time related text on the client.
