Hyperledger How to take DateTime input from user

Question

I want to enter the participant's Date of Birth as input but when I use the DateTime datatype the current date and time is auto inserted which I don't want. How can I do it?

There are tow options:

1. You can set it to a base epoch (yyyy-mm-dd):

 o DateTime datefield default="1970-01-01" or
 o DateTime datefield default="1900-01-01"

2. You can set it to nothing by using optional:

 o DateTime datefield optional

then you can input the right yyyy-mm-dd (DoB) format.
