Re: date Conversion Program in Assembly

Hi Ninad

Use this function i wrote:

; FILETIME structure
[St_DateTimeStamp:
St_DateTimeStamp.dwLowDateTime: D$ 0
St_DateTimeStamp.dwHighDateTime: D$ 0]



; SYSTEMTIME structure

[St_UTC:
St_UTC.wYear: W$ 0
St_UTC.wMonth: W$ 0
St_UTC.wDayOfWeek: W$ 0
St_UTC.wDay: W$ 0
St_UTC.wHour: W$ 0
St_UTC.wMinute: W$ 0
St_UTC.wSecond: W$ 0
St_UTC.wMilliseconds: W$ 0]



Proc TimeDateStampToString:
Arguments @TimeStamp, @DateFmt, @TimeFmt, @DateOut, @TimeOut

mov eax D@TimeStamp
mov edx &SECS_TO_100NS
mul edx


add eax &EPOCH_DIFF_SECS_INTERVAL_LOW
adc edx &EPOCH_DIFF_SECS_INTERVAL_HIGH


mov D$St_DateTimeStamp.dwLowDateTime eax
mov D$St_DateTimeStamp.dwHighDateTime edx

call 'kernel32.FileTimeToSystemTime' St_DateTimeStamp St_UTC

call 'KERNEL32.GetDateFormatA' &LOCALE_SYSTEM_DEFAULT &NULL
St_UTC D@DateFmt D@DateOut &MAX_UTC_TIME_LEN
call 'KERNEL32.GetTimeFormatA' &LOCALE_SYSTEM_DEFAULT &NULL
St_UTC D@TimeFmt D@TimeOut &MAX_UTC_TIME_LEN

EndP


Usage example:


[DataPointer: D$ ?] ; Points to the data that stored the value of the
timedate stamp.

[Sz_Year: B$ "yyyy/MM/dd ddd ",0]
[Sz_Hour: B$ "HH:mm:ss UTC",0]

[szDateString: B$ ? #64] ; Lenght of the date string. (Maximum is
&MAX_UTC_TIME_LEN)
[szTimeString: B$ ? #64] ; Lenght of the time string. (Maximum is
&MAX_UTC_TIME_LEN)


call TimeDateStampToString D$DataPointer Sz_Year Sz_Hour
szDateString szTimeString
