Time Simulator: Automate Virtual Clock Changes While Testing | What is Time Virtualization?
Time virtualization disintegrates the system clock into virtual clocks, independent of each others. Virtual clocks can be used in many situations for interactive teaching, time zone correction, server clock synchronization and, most importantly, temporal software testing to time travel applications.

What is Time Virtualization?

Time Virtualization is the Fastest and Most Secured Method to Test Applications Through Time.


What is Virtualization?

The definition of virtual includes “existing or occurring on the computer or Internet.” In simple tech terms, virtualization is simulating hardware and creating a virtual computer system using software.

Server virtualization allows businesses to reduce IT costs. It raises the efficiency, utilization and flexibility of hardware. Network virtualization and desktop virtualization are also available. These can create virtual clocks.


Time Virtualization

Time virtualization refers to virtue by which a system clock disintegrates into a number of smaller clocks which are independent of each other. This helps app testers add the dimension of time to their testing cycles.
For example, if an app wants to keep track of bill payments of a few customers, it needs to utilize different clocks for each customer. Here is where time virtualization steps in.
Time virtualization is a utility backed by leading software or hardware giants. With IBM funding heavily into time virtualization research in the 1970s-1980s, time virtualization has earned respect in the developing community.


The Virtualized Clocks

Virtual clocks can be used in many situations. Examples include interactive teaching, time zone correction, server synchronization and, most importantly, software testing.

How do they work? The system clock is dematerialized and multiplied to create independent virtual clocks. Neither code modification nor modification of the server clock is needed.


Functions of the Virtual Clock

Software virtualized clocks are essentially like time machines.

They enable you to time travel your applications to any point in time. Whether it is into the past or future, or in any environment, it’s all possible. For date and time sensitive application logic, clock virtualization is a crucial aid in time shift testing.
These include:

  • Month end, quarter end and year end processing
  • Billing cycle
  • Workflow
  • Policy life cycle


Benefits and Advantages

The virtual machine (VM) is the virtual computer system created. VMs make it possible to run multiple operating systems simultaneously on one server.

Using virtual clocks in time shift testing cuts down considerably on resources and costs.

Resetting the system clock is time-consuming and prone to error. In a Kerberos secured environment or under Active Directory, it’s not even possible. As mentioned above, virtual clocks remove the need to reset the system clock.
This lowers both the time needed and the possible risks. Engineering productivity is raised, hardware and software costs reduced, and security increased.


Common Software Tests with Virtual Clocks

Virtual clocks are fundamental tools in various tests. Below are a few common uses of our software.

  • SAP / ERP Testing: Organizations usually use a step-wise manner, since deploying a full SAP is complex. This is a complicated process with pricey risks. Virtual clocks can be used for future date testing. It virtually accelerates sessions by increasing clock speed, allowing faster deployment of SAP.


  • Migration Testing: Virtual clocks can test all date and time logic within a new or migrated environment. Unique and individual virtual dates and times are provided. A tester can run any module on any specific date. One can simulate an end-of-month while the other checks for year-end validity at once.


  • Regression Testing: This runs all existing tests to ensure changes won’t disrupt functionality. The flexibility provided by virtual clocks allows integration with test automation suites. All temporal test cases are tested for every change with ease.


  • Active Directory Testing: Active Directory is the central security control in Microsoft networks and mixed mode enterprises. However, the Kerberos authentication process prevents system clock changes for date and time test applications. Virtual clocks are the only solution to truly date test these applications. Security is maintained while applications “time travel.”


The advantages virtual clocks offer are endless, but also quite evident.

Because no hardware changes are necessary, virtualized clocks simplify processes, removing error-prone steps. This virtualization software allows you to complete projects before the deadline and under the budget.


The possibilities of using time virtualization are endless. It has already proven to give a huge boost to productivity while saving hardware and software costs while applied in a proper way.
