trouble with Time concersion between US time zones to UTC then converting to military time

[tammey1052]

I am attempting to take a meeting start and stop time, add an hour to the beginning and the end(autoScaling), convert those times from a user picked time zone (either et, ct, mt, or pt) to UTC, Then converting those two times to military time. and including a choice for daylight savings time or standard time

** It freezes when I get to the switch case ??????

// Assigning the Variables
int startTime;

int timezone;
char seasonal;
double autoScalingStart;
double autoScalingStop;
double meetingLength;



int main ()
{

// Input Daylight Savings Time or Standard Time

cout << "Enter 'd' for Daylight Savings Time or 's' for Standard Time." << endl <<
"Note: In 2020, Daylight Saving Time ends Sunday Nov 1:" << endl;

// Verrifying Meeting Length Information

while (seasonal == 's')
{
    autoScalingStart = (autoScalingStart + 1);
}

This is an infinite loop.
