I just used AltaVista advanced search and got the +# following count of page hits: +# +# 1,103 "Eastern Summer Time" AND domain:au +# 971 "Australian Eastern Summer Time" AND domain:au +# 613 "Eastern Daylight Time" AND domain:au +# 127 "Australian Eastern Daylight Time" AND domain:au +# +# Here "Summer" seems quite a bit more popular than "Daylight", +# particularly when we know the time zone is Australian and not US, +# say. The "Australian" prefix seems to be popular for Eastern Summer +# Time, but unpopular for Eastern Daylight Time. +# +# For abbreviations, tools like AltaVista are less useful because of +# ambiguity.
