QDateTimeEdit as a time in unix?

[kja]

Hi,

I want to have a user enter a QDateTimeEdit time and then take that info and convert it to unix time that I can store in a double so that I can load up some data. Any Idea how this can be done?

I was thinking I could get the info then convert it to a char * and then maybe convert it to unix? But that is probably totally wrong:

QDateTimeEdit * startTime;
startTime = new QDateTimeEdit;
 
//slot activated when user clicks a pushbutton)
void myWidget::getStartTime
{   
    QString stEntered =startTime->text();
    char * Start = qstrdup( stEntered.toLatin1() );
 
    /// then convert to unix...maybe
}

QDateTimeEdit * startTime;
startTime = new QDateTimeEdit;

//slot activated when user clicks a pushbutton)
void myWidget::getStartTime
{   
    QString stEntered =startTime->text();
    char * Start = qstrdup( stEntered.toLatin1() );
  
    /// then convert to unix...maybe
}

To copy to clipboard, switch view to plain text mode 

Is there a different/better way to convert some QDateTimeEdit to a double that will store the time in seconds since Epoch?

Thanks for the help.
