Skrev en datumklass i C# inspirerad av php motsvarande funktion, du kan ju kolla om du hittar något av värde...
/*
* Date class based on unix Epoch time stamp, second from 00:00:00 1/1 1970
*
* beta 1
*
** setDate(long second, long minute, long hour, long day, long month, long year)
* Sets Date variables can be overloaded, e.g. you can set 25 hours or -23 minutes //month don't work as negativ yet
* year: both full (4 digits) and short (2 digits) supported, years > 100 counts as full, years < 70 counts as years + 2000, years >= 70 and <= 100 counts as years + 1900
*
** addDate(long second, long minute, long hour, long day, long month, long year)
* Add Date value, same as above...
*
** setUDate(long unixStamp)
* Sets the unix time stamp directly
*
** addUDate(long unixStamp)
* Adds seconds to time stamp value
*
** setTimeZone(float timeZoneHour) ***Används ej i version
* Sets time zone as float of hours from +0000
*
** setTimeZoneSec(long timeZone) ***Används ej i version
* Sets time zone as int of seconds from +0
*
** string getDate(string referens)
* return string of wanted type, free formating, unknown chars passes through to string (very similar to the date() function in php)
*
* d : Day of the month, 2 digits with leading zeros, 01 to 31
* j : Day of the month, without leading zeros, 1 to 31
* S : English ordinal suffix for the day of the month, 2 characters, st for 1, nd for 2 and so on (works well with j)
* D : Day of the week, 3 letters, Mon to Sun
* l : Day of the week, full text, Monday to Sunday
* w : Day of the week, number, 0 (monday) to 6 (sunday)
* z : Day of the year, number, 0 (1 jan) to 364 (365 if leap)
* W : Week of the year, number, starting on 1
* F : Month, full text, January to December
* M : Month, 3 letters, Jan to Dec
* m : Month, 2 digits with leading zeros, 01 to 12
* n : Month, without leading zeros, 1 to 12
* t : Days in current month, 28 to 31
* L : returns 1 if leap year, else 0
* Y : Year, full 4 digits, e.g. 1999 / 2005
* y : Year, short 2 digits, e.g. 99 / 05
* o : Year as "Y", but day which week is in past year count as that year e.g. the date 1 jan 2006 will return 2005 with "o"
* a : Lowercase am or pm
* A : Uppercase AM or PM
* g : 12 hour clock, without leading zeros, midnight 0, noon 12
* h : 12 hour clock, with leading zeros, midnight 00, noon 12
* G : 24 hour clock, without leading zeros, 0 to 23
* H : 24 hour clock, with leading zeros, 00 to 23
* i : Minutes with leading zeros, 00 to 59
* s : Seconds, with leading zeros, 00 to 59
* e : //none
* I : //none
* O : Difference to Greenwich time (GMT) in hours, e.g. +0200 or -0300
* Z : Timezone offset in seconds. e.g. -21600 or 10800
* U : Seconds since the Unix Epoch (January 1 1970 00:00:00 GMT)
* { : Char after "{" passes direct to out string, e.g. {YY returns Y2006 (if it's 2006)
*
