The maximum is billions of years in the +future, but this is a theoretical limit as the computation of that year +would take too long with the current implementation of adodb_mktime(). + +This library replaces native functions as follows: + +
+	getdate()  with  adodb_getdate()
+	date()     with  adodb_date()
+	gmdate()   with  adodb_gmdate()
+	mktime()   with  adodb_mktime()
+	gmmktime() with  adodb_gmmktime()
+	strftime() with  adodb_strftime()
+	strftime() with  adodb_gmstrftime()
+
+ +The parameters are identical, except that adodb_date() accepts a subset +of date()'s field formats. Mktime() will convert from local time to GMT, +and date() will convert from GMT to local time, but daylight savings is +not handled currently. + +This library is independant of the rest of ADOdb, and can be used +as standalone code. + +PERFORMANCE + +For high speed, this library uses the native date functions where +possible, and only switches to PHP code when the dates fall outside +the 32-bit signed integer range. + +GREGORIAN CORRECTION + +Pope Gregory shortened October of A.D. 1582 by ten days.

+	%r - time in a.m. and p.m. notation
+	%R - time in 24 hour notation
+	%S - second as a decimal number
+	%t - tab character

+	%g - like %G, but without the century.
+	%G - The 4-digit year corresponding to the ISO week number (see %V).
+	     This has the same format and value as %Y, except that if the ISO week number belongs
+		 to the previous or next year, that year is used instead.
+	%j - day of the year as a decimal number (range 001 to 366)
+	%u - weekday as a decimal number [1,7], with 1 representing Monday
+	%U - week number of the current year as a decimal number, starting

+	%V - The ISO 8601:1988 week number of the current year as a decimal number,
+	     range 01 to 53, where week 1 is the first week that has at least 4 days in the
+		 current year, and with Monday as the first day of the week. (Use %G or %g for
+		 the year component that corresponds to the week number for the specified timestamp.)
+	%w - day of the week as a decimal, Sunday being 0
+	%W - week number of the current year as a decimal number, starting with the
+	     first Monday as the first day of the first week
