Since no inhabited place on Earth still officially uses local mean time, the correct answers depend on which countries or parts of countries are along each longitude and what time zones those countries have chosen to use. Another fact that affects the answers is that Greenwich observes Summer Time (a.k.a. Daylight Saving Time) from late March until late October. During Summer Time, 12:00 BST at Greenwich equals 11:00 UTC.
