Did the same thing against my local google.ca site, and against google.ie for
comparison, and report the (very slightly) lower number for every query, also
including omitted results, and navigated to the last displayable page of those
to get actual matches, as estimated hits are always inflated (sometimes greatly,
as in these queries with your last quoted numbers) and may reflect all documents
with some words in the query.
Some pages discuss IST, but I see some, and assume most, of those are counted in
all queries where IST is not included in the quoted search phrase.


base/+omitted (navigating to last displayable page to get actual matches)
 no site	site:ie		query
 72/ 425	 82/198		Irish+Summer+Time+IST
 61/ 388	 19/ 61		"Irish+Summer+Time"+IST
 55/ 322	 31/ 77		Irish+Standard+Time+IST
 55/ 312	 32/111		"Irish+Standard+Time"+IST
 53/ 399	  9/ 18		"Irish+Summer+Time+IST"
 51/ 391	 20/ 66		"Irish+Standard+Time+IST"

186/1212	110/277		Summer
161/1025	 83/254		Standard

My conclusion is that somewhat more writers in general seem to make the natural
assumption that "S" is *Summer*, as in the UK and other places where use of
/daylight saving/ is uncommon, but more writers on IE sites may know that "S" is
*Standard*, from the higher ratios of matches on the quoted phrases.

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
