Sorry if this question was asked many times but did not find in FASM manual and not in search MAIN.

How can I obtain date and time information during compilation ?
I want to build a date/time string of compilation date like

yyyymmddhhmmss

Something like that.
Does ist exist ?

Shocked

Thanks, Tom

the easy way would be to do it by hand, with a pencil on a sheet of paper.
for the hard way, i don't have ideas, wait for experts to have a better answer.

all in all, i like my answer, i find it cool.

Using windows...

Code:

_st SYSTEMTIME 

push _st
call [GetLocalTime]

mov eax,_st

[eax+SYSTEMTIME.wDay]  => Day | ie Monday, Tuesday..etc
[eax+SYSTEMTIME.wDate] => Date
[eax+SYSTEMTIME.wHour] => Hour
....
or

[_st.wXXX]

Okay typedef, how can windows obtain the compilation date / time of binary compiled by FASM ?

search the forum, there were several macros for it.

PS: At first I saw topic "how to get date during compilation", then I was disappointed Very Happy

You can use the built in %t timestamp:
Code:
_t = %t

_t_s =  _t mod 60
_t_m = ((_t - _t_s) / 60) mod 60
_t_h = ((_t - (_t_m * 60) - _t_s) / 3600) mod 24

db '0'+(_t_h  /  10)
db '0'+(_t_h mod 10)
db ':'
db '0'+(_t_m  /  10)
db '0'+(_t_m mod 10)
db ':'
db '0'+(_t_s  /  10)
db '0'+(_t_s mod 10)
    
You should be able to get the date form this as well.

Sorry to interfere but i must correct your code...

1) st is reserved FPU register, it must have new name (eg: _st)
2) Name goes before struct type (eg: _st SYSTEMTIME)
3) No need to use EAX (eg: [_st.wDay] is simpler)

Just thought i would help (to keep OP from chasing ghosts) Smile

Thank you for that code snippet.
I tried myself with %t.
Is not comfortable because have to write own macro but now I have following problem.

My computer dumps out date/time at GMT.
There is a difference of 2 hours to Berlin time because of other timezone and DST (daylight saving time) active.

So my computer writes 14.06.2011 22:25:00.
Of course when I look at my PC clock it is 15.06.2011 00:25:00

Any idea to solve this problem ? Shocked

Should I open a new thread with this more specific problem ? Very Happy

You'd have to manually adjust the timestamp to your time zone and "daylight saving time" state. You can do this by simple arithmetic:
Code:
_t = %t + (+2 * 3600)

Okay but what happen when DST switched off ?
I now how I can manipulate data but thought there would be a more comfortable way.

Thank you bitshifter... I knew all that but I forgot because I just came HLL programming...lol Very Happy

you can see the way I declared system time

I forgot it's var DATA_TYPE

In C/C++/Java you know it's data_type var...

Sorry for that confusion and thank you bitshifter

shutdownall, wouldn't be better to just stick with the GMT time (which is DST invariant)? The reason I have against local time is that when transitioning from DST back to normal time zone there are 60 minutes of a day that occurs twice, so you could end up with a latest compilation being "older" than a previous one (unless you add to your format a DST indicator).
