Title: How to use TimeStamp for our application
Question: How to use TimeStamp for our application
Answer:
Here're the functions
1. Count Days between Date1 and Date2 -(1/1/01 - 4/4/01) = 94 Days
If you use DecodeDate, it'll be hardway for you. In this case we can use TimeStamp for ease.
Example :
Function TForm1.CountDays(d1,d2:TDate):integer;
var
xD1,xD2:longint;
begin
xD1:=DateTimeToTimeStamp(d1).date;
xD2:=DateTimeToTimeStamp(d2).date;
Result:=(XD2-XD1)+1;
end;
2. Count Hours between Time1 And Time2 -(01:00 AM-04:30 AM) = 4.5 Hours
Example :
Function TForm1.CountHour(t1,t2:TTime):single;
var
xT1,xT2:single;
begin
xT1:=DateTimeToTimeStamp(t1).time;
xT2:=DateTimeToTimeStamp(t2).time;
if xT1xT2 then
if xT2 xT1:=xT1-43200000;
xT2:=xT2+43200000;
Result:=abs((xT1-XT2)/3600000);
end
else result:=abs(12-(xT1-XT2)/3600000)
else
Result:=abs(((xT1-XT2)/3600000));
end;
