Answer 1

MS Excel stores the dates as float values. The integer part represents the days and the fractional part keeps the hours, minutes and seconds.

Check this code that extracts the hours and also the minutes and seconds, maybe you need them:

float excelValue = 0.4f;

int miliseconds = (int)Math.Round(excelValue*86400000);
int hour = miliseconds/( 60/*minutes*/*60/*seconds*/*1000 );
miliseconds = miliseconds - hour*60/*minutes*/*60/*seconds*/*1000;
int minutes = miliseconds/( 60/*seconds*/*1000 );
miliseconds = miliseconds - minutes*60/*seconds*/*1000;
int seconds = miliseconds/1000;
