 How to convert from double type time to Date format? |

Hello,
ChartDirector seems to use time to convert to double type like the code below.
SYSTEMTIME st;
GetLocalTime (& st);
double now = Chart :: chartTime (st.wYear, st.wMonth, st.wDay, st.wHour, st.wMinute, st.wSecond) + st.wMilliseconds / 1000.0;
My question is two:
1) I want to know the code that reverses this double type to Date format.
2) Does ChartDirector have a function that converts double type time to Date format?
Regards,
Cho |

Hi Cho,
You may use the following method:
// Get the date as a number with 8 decimal digits reprensenting yyyymmdd
int yyyymmdd = Chart::getChartYMD(now);
int yyyy = yyyymmdd / 10000;
int mm = (yyyymmdd % 10000) / 10;
int dd = yyyymmdd % 100;
// To get the hh:nn:ss, you can use the following method (86400 is the number of seconds in 1 day)
int hh = (int)(fmod(now, 86400)) / 3600;
int nn = (int)(fmod(now, 3600)) / 60;
double ss = fmod(now, 60)
Hope this can help.
