Manipulate SYSTEMTIME ?

[Stephane Paquin]

Hi!

I try to add/substract a number of days(or hours ,minutes
,seconds) to a SYSTEMTIME time. How do you d that using the Win32 API?

I am using Digital Visual Fortran and don´t have access to 64
bit integers. What can I do ?

I know that VB has built-in functions to do that. VC has a
TIME class to manipulate time. It seems that Win32 api doesn´t do time
manipulation.

Thank you.

Can FileTimeToSysTime do?

FileTimeToSystemTime only transforms a time value from FILETIME to
SYSTEMTIME structure. I still have not added or substracted days (or
hours ,minutes, seconds...).

Even if I transform to FILETIME, how can I manipulate the time
to add or substract ? Remember I don´t have access to quadwords in
DVF. It seems to me there is a big hole in Win32 api.

Stephane,

(a) write a DLL in some other language

(b) regard the 64bit int as two 32bit unsigned ints:
total = hiword*2**32 + loword
