I am putting together a program in C++ and have run into some problems with dates and times.

First off the biggest problem,
I need to take the current (each time a button is clicked) system time and assign it to a variable.
how do i get the system time? and what format will it be in?

after that i need to do some work with the value of the variable that i think i can handel.

2nd
I have a DateTimePicker in the program for the user to select another time from.
when run it will only cycle upto 23 or down to 1 it will not go to 00 in either direction,
only way i have found to sort this is to change ShowCheckbox to true,
this adds a little checkbox to the left of the time but i dont want it on view,
other programs i have seen cycle through 00 ok with this checkbox in view.

Any pointers greatly recieved.
Thanks

Click to expand...

We are talking windows api here? If so use GetSystemTime.

Code: 
SYSTEMTIME time;
GetSystemTime(&time);

SYSTEMTIME is a structure, to get at the components do this

Code: 
int iHours = time.wHour;
int iMinutes = time.wMinute;
int iSeconds = time.wSecond;
int iMilliSecondss = time.wMilliSeconds
