IBM Hourglass for date and time simulation
IBM® HourGlass is a clock simulator for testing mainframe applications. It enables you to simulate date and time—past, present or future—without changing application code or requiring a separate computing environment. You can coordinate functionality across time zones to strengthen the thoroughness of application testing and improve the accuracy and reliability of mission-critical applications.
Improve accuracy, reliability
Simulate any date and time that can be represented by the underlying computer hardware. Thoroughly test time-sensitive applications to help avoid costly issues after deployment.
Boost testing efficiency
Automate the date and time testing process to help deliver reliable applications without requiring changes to application code, re-IPLing the CPU or LPAR or making runtime JCL changes.
Identify applications that request the system date and time and resolve potential problems before they occur.
