3) What's the deal with "today"? It seems to be a synonym for
"current
date" when used in comparisons, but doesn't seem to be valid anywhere
else.
I use today as a variable for current date; i.e.,
set today to (current date)
I then use it for various forms of date comparisons. The reason I do
this is that current date returns the date, exact to the second, each
time it is called, so if you call it more than once in a script, it
may give different results each time.
As others have mentioned, the date in seconds depends on the epoch used.
I'm not sure, but I think that the Jan 1, 1904 beginning date of the
Mac's epoch was done away with in OS X.
set x to "july 4, 1776"
(date x)
--> date "Thursday, July 4, 1776 12:00:0 AM"
set x to "july 4, 1776"
(current date) - (date x)
--> 7.262679661E+9
set x to "july 4, 1776"
set y to "July 4, 2006"
set z to (current date) - (date x)
(z / days) / 365.24
--> 230.14674077826
But that is some 53 days off; when did the US move from the Julian
calendar to the Gregorian? And how many days difference did that cause?
