# ================= Problem Description =================
# This script calculates and displays the delivery time or date based on the order time.
# The delivery time is determined as follows:
# - If the order time is less than 6 hours, the delivery time is the current date.
# - If the order time is 6 hours or more, the delivery date is the following day.
# 
# 1. Prompts the user to input the order time in hours.
# 2. Calculates the delivery time or date based on the order time.
# 3. Displays the result.
# 4. Asks the user if they want to retry or quit.
#
# The program continues to prompt for new order times until the user decides to quit or provides invalid input.
#
# ================= Input =================
# - Order time (integer value representing hours).
#
# ================= Output =================
# - Delivery time or date based on the order time.
# - Option to retry or quit after each result.
#
# Example:
# Input:
# Enter order time: 3
# Output:
# Delivery time is: 2024-09-16
# Do you want to retry? (y/q): n
# =========================================================
