Nice! I've thought about a vertical UI like this for the last 2 years but was never happy with the html mockups (my last mockup: http://www.txtlabs.com/tzs/ http://www.txtlabs.com/tzs/), so I know this UI is hard to get right. Suggestions: - simple buttons for next/previous day & today - make date boundaries more prominent - speed - do everything in JavaScript - site should become purely static as a nice bonus - drop-down of ordered timezones as an alternative entry option Question for HN: how would you monetize a simple site this? ads? or not at all?
