Like the title, sometime I want store compile Time and Date to my executable but I can't find that constant in FASM.PDF document.

Could it will appear on next ver of FASM? Very Happy

Please have a look at the old thread about computing date elements from %T value: http://board.flatassembler.net/topic.php?p=8558#8558

Actually %t is not a constant. It can be different each time you read it.

I remember once I suggested a solution to the changing time problem.

Just as fasm's "numerical constants" are in fact numerical variables.
Is there an actual problem that this causes? Other than a slight abuse of the SSSO principle, but this is actually a problem with %t in any variant.

I'm not aware of any existing code where this causes a problem, just the potential for a future gotcha for anybody unaware of the behaviour.
