Choose a Time Zone: Scroll through the list and select the time zone you wish to view. The list includes various cities and regions, each followed by its respective UTC offset (e.g., “(UTC-05:00) Eastern Time (US & Canada)”).

Step 3: View the Current Time

Once you select a time zone, the following information will be updated in real-time:

Location Name: The name of the selected time zone will appear in large text at the top of the clock container, replacing “Select Timezone.”

Usage: Implemented to make better use of daylight during the longer days of summer. Clocks are typically set forward one hour in the spring and set back one hour in the fall.
Benefits: Provides more daylight in the evening, which can reduce energy consumption and provide more opportunities for outdoor activities.
Challenges: Can disrupt sleep patterns and schedules, leading to potential health and productivity impacts.
