While the app is handy for seeing the differences between cities/time zones for the current day, the app does not properly recognize when daylight savings time changes in the future between different countries. E.g.: the UK falls back on the last Sunday in October, but the US falls back on the first Sunday in November; the app thinks theres still 8h of difference between Los Angeles and London on October 31, when there should only be 7h difference.
The app could allow easier selection of a different date than just +/- 1 day; its too easy to double click the wheel instead, thereby resetting the date to now.
