In Ask Ubuntu, there are limits on how many things you can do each day. For example:
- You can only flag 36 items per day,
- You can only review 20 items from one category per day,
- You can only get 200 reputation per day, and
- You can only use 40 votes per day.
As well as opportunities to receive badges within a set time period, like:
Those are all the badges that have a requirement of doing a task in a time frame.
Since Ask Ubuntu is a very vibrant place with many nationalities and cultures, it's quite obvious that not everyone is in the same time zone.
So, what time zone does Ask Ubuntu use to determine a 'new day' or a 24-hour period? Do they use a clock at all, or do they measure the time in your time zone and count on another 24 hours?
