Hello everyone!
In the "TimeDataStamp" field of executable files exe\dll\sys, the time is stored in 32-bit Unix format (dword). How can I convert the current system time (UTC) to write it to the "TimeDateStamp" field of the file's PE header? I looked for a function among Win32API, but it seems there is no such function. The source code of the FASM compiler should contain this procedure - help me find it. Thank you.

It is possible to use GetSystemTimeAsFileTime and divide by 10^7 to get seconds since the epoch. Then adjust the epoch by adding/subtracting some seconds to put it into the wanted timezone.

@revolution - great!
I just found it on the Microsoft website, only this is the reverse conversion from TimeDataStamp to FileTime.

I wonder why engineers didn't introduce a special API for this, otherwise it turns out there is time, but no function (you have to do it manually).

I find the search engines to be "less good" when searching for technical information. It's better to read the manuals and docs, or ask a real person (like on this board), than to rely on an Internet search to uncover something, IMO.

Many of the popular engines available today are becoming more focussed on displaying sales sites in preference to informational sites.
