new variables {__YEAR__} {__MONTH__} {__DAY__}

I made a custom version of MakeNsis.exe 201 to solve a reversioning problem.
I added 3 predefined variables.

!define ${PRODUCT_VERSION} "${__YEAR__}.${__MONTH__}.${__DAY__}" 
;-> 4.10.02 

In the script.cpp, 2 modified functions:

void CEXEBuild::set_date_time_predefines()
{
  time_t etime;
  struct tm * ltime;
  char datebuf[128];
  char timebuf[128];
  char yearbuf[128];
  char monthbuf[128];
  char daybuf[128];
  time(&etime);
  ltime = localtime(&etime);
#ifdef _WIN32
  SYSTEMTIME stime;
  stime.wYear = ltime->tm_year+1900;
  stime.wMonth = ltime->tm_mon + 1;
  stime.wDay = ltime->tm_mday;
  stime.wHour= ltime->tm_hour;
  stime.wMinute= ltime->tm_min;
  stime.wSecond= ltime->tm_sec;
  stime.wMilliseconds= 0;
  GetDateFormat(LOCALE_USER_DEFAULT, DATE_SHORTDATE, &stime, NULL, datebuf, sizeof(datebuf));
  definedlist.add("__DATE__",(char *)datebuf);
  GetTimeFormat(LOCALE_USER_DEFAULT, 0, &stime, NULL, timebuf, sizeof(timebuf));
  definedlist.add("__TIME__",(char *)timebuf);
  GetDateFormat(LOCALE_USER_DEFAULT, 0, &stime, "y", yearbuf, sizeof(yearbuf));
  definedlist.add("__YEAR__",(char *)yearbuf);
  GetDateFormat(LOCALE_USER_DEFAULT, 0, &stime, "MM", monthbuf, sizeof(monthbuf));
  definedlist.add("__MONTH__",(char *)monthbuf);
  GetDateFormat(LOCALE_USER_DEFAULT, 0, &stime, "dd", daybuf, sizeof(daybuf));
  definedlist.add("__DAY__",(char *)daybuf);
#else
  my_strftime(datebuf, sizeof(datebuf), "%x", ltime);
  definedlist.add("__DATE__",(char *)datebuf);
  my_strftime(timebuf, sizeof(timebuf), "%X", ltime);
  definedlist.add("__TIME__",(char *)timebuf);
  my_strftime(yearbuf, sizeof(yearbuf), "%y", ltime);
  definedlist.add("__YEAR__",(char *)yearbuf);
  my_strftime(monthbuf, sizeof(monthbuf), "%m", ltime);
  definedlist.add("__MONTH__",(char *)monthbuf);
  my_strftime(daybuf, sizeof(daybuf), "%d", ltime);
  definedlist.add("__DAY__",(char *)daybuf);
#endif
}
void CEXEBuild::del_date_time_predefines()
{
  definedlist.del("__DATE__");
  definedlist.del("__TIME__");
  definedlist.del("__YEAR__");
  definedlist.del("__MONTH__");
  definedlist.del("__DAY__");
} 

i would cool if you can include this in the next release

Some times we like "${__YEAR__}.${__MONTH__}.${__DAY__}" but not "${__YEAR__}-${__MONTH__}-${__DAY__}" it's usefull. Hope include in the next release. 🙂

I think it would be best to make a define switch, or a new command that allows the user to select his own format. That'd also allow to get different times in different places in the script.
