Blank dates displaying as 1970



As per Pega suggestion mentioned in the following link:

the dynamic system setting (DSS) "disableEpochDateTime" was set to true but it still displays a blank date as 1970.

Error Messages

Not Applicable.

Steps to Reproduce

Perform the following local-change steps:
  1. Do a SET action in a DataTransform to set a Date property (say A) using another property (say B).
  2. At runtime if property B is blank then A will be set to the value 01-jan-1970.

Root Cause

disableEpochDateTime is applicable only for the integration layer which relies on following api internally - 

As far as the SET action/property-set methods in the clipboard layer return the default value for properties of type DateTime and the default value is 01-jan-1970. It is expected behavior that the clipboard layer will not return an empty value.


Add a when condition before the SET action to check if the value is blank or not. If the value is blank then skip the step.
