Class CTimestamp

CTimestamp represents a timestamp.

Part of this class was adapted from the ADOdb Date Library ADOdb abstraction library. The original source code was released under both BSD and GNU Lesser GPL library license, with the following copyright notice: Copyright (c) 2000, 2001, 2002, 2003, 2004 John Lim All rights reserved.

This class is provided to support UNIX timestamp that is beyond the range of 1901-2038 on Unix and1970-2038 on Windows. Except CTimestamp::getTimestamp(), all other methods in this class can work with the extended timestamp range. For CTimestamp::getTimestamp(), because it is merely a wrapper of mktime http://php.net/manual/en/function.mktime.php, it may still be subject to the limit of timestamp range on certain platforms. Please refer to the PHP manual for more information.

Algorithm from PEAR::Date_Calc Parameters `$year` `integer` $year year `$month` `integer` $month month `$day` `integer` $day day Returns `integer` day of week
`public static boolean`	# `isLeapYear( integer $year )` Checks for leap year, returns true if it is. No 2-digit year check. Also handles julian calendar correctly. Checks for leap year, returns true if it is. No 2-digit year check. Also handles julian calendar correctly. Parameters `$year` `integer` $year year to check Returns `boolean` true if is leap year
`protected static integer`	# `digitCheck( integer $y )` Fix 2-digit years. Works for any century. Assumes that if 2-digit is more than 30 years in future, then previous century. Fix 2-digit years. Works for any century. Assumes that if 2-digit is more than 30 years in future, then previous century. Parameters `$y` `integer` $y year Returns `integer` change two digit year into multiple digits
`public static integer`	# `get4DigitYear( integer $y )` Returns 4-digit representation of the year. Returns 4-digit representation of the year. Parameters `$y` `integer` $y year Returns `integer` 4-digit representation of the year

`public static array`	# `getDate( integer\|boolean $d = false, boolean $fast = false, boolean $gmt = false )` Returns the getdate() array. Returns the getdate() array. Parameters `$d` `integer\|boolean` $d original date timestamp. False to use the current timestamp. `$fast` `boolean` $fast false to compute the day of the week, default is true `$gmt` `boolean` $gmt true to calculate the GMT dates Returns `array` an array with date info.
`public static boolean`	# `isValidDate( integer $y, integer $m, integer $d )` Checks to see if the year, month, day are valid combination. Checks to see if the year, month, day are valid combination. Parameters `$y` `integer` $y year `$m` `integer` $m month `$d` `integer` $d day Returns `boolean` true if valid date, semantic check only.
`public static boolean`	# `isValidTime( integer $h, integer $m, integer $s, boolean $hs24 = true )` Checks to see if the hour, minute and second are valid. Checks to see if the hour, minute and second are valid. Parameters `$h` `integer` $h hour `$m` `integer` $m minute `$s` `integer` $s second `$hs24` `boolean` $hs24 whether the hours should be 0 through 23 (default) or 1 through 12. Returns `boolean` true if valid date, semantic check only.
`public static string`	# `formatDate( string $fmt, integer\|boolean $d = false, boolean $is_gmt = false )` Formats a timestamp to a date string. Formats a timestamp to a date string. Parameters `$fmt` `string` $fmt format pattern `$d` `integer\|boolean` $d timestamp `$is_gmt` `boolean` $is_gmt whether this is a GMT timestamp Returns `string` formatted date based on timestamp $d
`public static integer\|float`	# `getTimestamp( integer $hr, integer $min, integer $sec, integer\|boolean $mon = false, integer\|boolean $day = false, integer\|boolean $year = false, boolean $is_gmt = false )` Generates a timestamp. This is the same as the PHP function mktime http://php.net/manual/en/function.mktime.php. Generates a timestamp.
