Webster's (an American English dictionary; Collegiate edition) says: * daylight saving time: time usually one hour ahead of standard time -- called also daylight time. * savings: money put by. * summer time: chiefly British: daylight saving time. * summertime: the summer season or a period like summer. * wintertime: the season of winter. * winter time: [not in the dictionary]. Interestingly, I found in a British dictionary from Penguin Books: * summer-time: system whereby clocks are put one hour ahead in summer; summer. Yes, with a hyphen and meaning both, i.e. the American summer time & summertime. Factoid for translators: In the Dutch language (spoken in The Netherlands and in Belgium - Flanders) we call DST "zomertijd" and standard time "wintertijd". Oscar van Vlijmen 2005-06-06
