HourGlass

Ensure the accuracy of time-sensitive applications

HourGlass is a z/OS system application, allowing sites to alter the Date/Time returned to a z/OS application when a time request is made (SVC 11 or PC Time Requests).

  • Patterns or specific applications, transactions, users, and address space names can be specified to limit the scope at which HourGlass will alter returned date/time information.
  • IBM HourGlass accurately simulates date and time processing for thorough application testing.
  • Coordinates reporting and data transfers across time zones.
  • Identifies applications that request the system date and time, and resolve potential problems before they occur.

Features and benefits

Time dimensional testing is essential for delivering reliable applications. All mission-critical enterprise applications are sensitive to date and time processing.

Date handling for online transaction processing must be 100% accurate to support banking, financial, healthcare, inventory management, insurance, utility and other customer-facing applications. Whether your applications are calculating interest payments or processing quarterly financial statements, errors in date handling can have serious negative consequences. Without a way to accurately test date- and time-sensitive applications, companies risk losing customers and revenue opportunities. In some cases, they can even face legal implications.

IBM HourGlass is the most widely used z/OS clock simulator for testing mainframe applications. HourGlass features and flexibility ensure easy, accurate and comprehensive application testing. As the proven solution of choice for system clock simulation, HourGlass helps you fast forward your applications for reliable, time-dimensional testing.

With HourGlass, many developers can run tests simultaneously – each using a different system date. HourGlass maintains each user’s view of the system date without affecting other users. More testing can be accomplished in a compressed timeframe. HourGlass supports time-dimensional testing in IBM’s CICS Open Transaction Environment (OTE) to take advantage of threadsafe improvements in CICS TS V2.2. It also provides enhanced support for applications that use IBM’s Language Environment (LE) for date services. IMS users can set the IMS IOPCB date and time fields to any requested date and time without having to re-link the application.

In addition, CICS users can set the EIBDATE field. Finally, HourGlass interfaces easily with third party products, testing with speed and accuracy. After successfully demonstrating its value during the Y2K conversion effort, HourGlass continues to ensure the accuracy of new and enhanced date- and timesensitive applications. That is why HourGlass is the most widely used date/time simulation tool in its class. Hour Glass improves the testing process and helps you deliver reliable applications.
