Unix timestamp on visual c++
- Thread starter datapath
- Start date
"the present time": at run-time or at compile-time?
"unix timestamp": not sure what you mean by this? Do you mean a Unix timestamp format?
I suspect you want the [tt]__TIME__[/tt] and [tt]__DATE__[/tt] predefined macros (if you want the compile-time information; or the [tt]asctime()[/tt] function (from [tt]time.h[/tt]) if you want it at run-time.

In the game of life the dice have an odd number of sides.

I need the time at run-time, and unix timestamp is the number of seconds elapsed since 00:00, january 1, 1970.
I think that the standard C function "time" is implemented in visual c++ and will do it for me. Gonna try it.
Thanks for your attention.

Sorry that this is a bit blunt:
If you had an idea about the [tt]time[/tt] function, datapath, why ask the question you did. I looked at the documentation and found this:
__________________________________________________________
time
Gets the system time.
Routine: [tt]time[/tt]
Required Header: [tt]<time.h>[/tt]
Compatibility: ANSI, Win 95, Win NT
Return Value
[tt]time[/tt] returns the time in elapsed seconds. There is no error return.
Parameter
[tt]timer[/tt] -- Storage location for time
Remarks
The [tt]time[/tt] function returns the number of seconds elapsed since midnight (00:00:00), January 1, 1970, coordinated universal time, according to the system clock. The return value is stored in the location given by [tt]timer[/tt]. This parameter may be [tt]NULL[/tt], in which case the return value is not stored.

Seems it does exactly what you want.
