This library overcomes these limitations by replacing the -native function's signed integers (normally 32-bits) with PHP floating -point numbers (normally 64-bits). - -Dates from 100 A.D. to 3000 A.D. and later -have been tested. The minimum is 100 A.D. as <100 will invoke the -2 => 4 digit year conversion. 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: - -<pre> - 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() -</pre> - -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.
