Empty DateTime property returns date as 19700101T000000.000



As per the Pega documentation, the disableEpochDate and disableEpochDateTime Dynamic System Settings (DSS) are set to true. However, an empty DateTime property displays 19700101T000000.000

Error Messages

Not Applicable

Steps to Reproduce

Perform a SET action in a data transform to set a Date property (for example, A) using another property (for example, B).

At runtime, if property B is blank, then A is set to 01-jan-1970 value.

Root Cause

The disableEpochDateTime is applicable only for the Integration layer which relies on the following API internally.

The SET action or property-set methods in the Clipboard layer return the default value for properties of type DateTime and the default value is 01-jan-1970. The Clipboard layer will not return an empty value.


Perform the following local-change:

Add a When condition before the SET action in the data transform to determine if the value is blank or not. Skip the step if the value is blank.
