So, I had a massive rethink of the timezones page and I present to you:
It tells you your current time, the current time in UTC.
More importantly it now also lets you enter a time and date in UTC and see it in your timezone, or enter one in your timezone and see it in UTC.
No more thinking is required!
If you feel it didn't live up to my H1 hype, tell me what you think can change :)
