This next package allows you to create different Clock objects, and initialize each one to a specific time zone. In this way, Dev Shed has established a reputation second to none in the IT industry for information on today’s best known open source and enterprise technologies.
This comes in handy in situations where you need to spawn more than one instance of an object — for example, two simultaneous database links for two simultaneous queries, or two shopping carts.
