The My Time to US table converts a user's local time to the corresponding time in a US location based on the ZIP code. It records the user's local time, the target ZIP code, the time zone offset of that ZIP code, whether DST is in effect, and the resulting local time in the US location. This table is essential for determining what time it will be in a specific US location when it's a particular time in the user's location.
The US Time to My table performs the reverse operation, converting a time in a US location to the user's local time. It records the local date and time in the US location, the ZIP code, time zone offset, DST status, and the resulting time in the user's location. This table is crucial for understanding what time it will be locally when it's a specific time in a US location.
The US ZIP Codes table contains essential geographic information for each ZIP code, including the city, state, latitude, longitude, whether the area observes DST, and the time zone offset. This table provides the foundational data necessary for the time conversion processes in the other tables, ensuring that time calculations are accurate based on the location's geographical and temporal attributes.
Overall, this database offers a reliable system for converting times between a user's local time and various US time zones, making it a valuable tool for anyone who needs to coordinate across different time zones in the United States.
