[Question/Feat Request]Mapping multiple JSON properties  to one object property

Mapping multiple JSON properties  to one object property

For example I have the following JSON object:
`obj = {
id: '002',
date: '05/07/1991',
time:'22:35'
`
And I want to map it to the following class :
`class Example {
 @JsonProperty()
 id = '';
datetime: Date = new Date();
}`
I want to concatenate date and time to datetime. Ho would I go about acomplishing this?
