How can i interpret “FoxPro” dbf file date time field (eight-byte) in my c++ program?

问题

I am writing a c++ program to read DBF file of foxpro database .I stumbled upon this date time field of eight bytes.How can i interpret it ? Any help would be highly appreciated ?

回答1:

The value is a double

The integer part is the day since 1899/12/30

internal const double JulianDay_1899_12_30 = 2415019.0;

double d = theValue;

in c#

return DateTime.FromOADate(d - JulianDay_1899_12_30);
