Date Value Modifier processing element can be used to increment or decrement the value of a given input date string. The input can be set as a message context scope variable, message property, message transport header or users can directly provide the relevant date string as a property to the processing element configuration. If you are using a scope variable or a message property to provide the input date it can be a java.util.Date type or java.lang.String type. In the processing element configuration you can define the segment of the date to be modified and number of units that it needs to be modified. Also you can define where the resultant modified date should be assigned to, ie: to a scope variable, message property or a message header, and the name of the parameter which will hold the result.

The processing element will modify given date by the defined number of units and then assign it to a variable/property/header and then it will be forwarded to this out port |

The following simple use case describes how you can receive a HTTP message which contains a transport header with a timestamp value and how you can modify it as you prefer and use in your custom logic. In this case modified date will be assigned to a message context scope variable.
In the above flow, through HTTP Ingress Connector element messages will be received to the flow. Each message will have a transport header "timestamp" that contains a date value formatted into "yyyy-MM-dd’T’HH:mm:ss". From that date Date Value Modifier processing element will modify inorder to increment the day value from four units and assign it to a scope variable of name "updatedDate".
Following images depicts configuration of the processing element.
After modification, modified date will be assigned to a scope variable as depicted in the following image.
After modification, in this simple message flow, the message will be forwarded to the backend server through a HTTP Egress Connector.
