Chasing the sun

James and I have been tracking Jamie's journey to New Zealand using the planefinder app. Last night we tracked him as he headed north and crossed Greenland before curving south towards Los Angeles. This morning we saw that his plane had left Los Angeles to head westwards to Auckland. Because he was heading west he kept ahead of the sunset for quite a while. When he crosses the date line as he approaches New Zealand he will suddenly lose a whole day as the clock jumps a whole 24 hours forwards! How weird is that? Then there will be one more change - an hour backwards - so when he is in New Zealand he will be 11 hours ahead of us here in Scotland!
