botframework : the date time is taken into account while running test

Hello,

I have used the sample from botframwork of testmybot and pluged it with my personnal bot. But my bot is sending images wich are stored as json in the .txt file for the test.

When I am running the npm run test command, I got the following fail :
`Failures:
1) TestMyBot Test Suite for testmybot-sample-botframework basic_test
Message:
Failed: basic_test/Line 129: Expected bot response "2018-06-21T08:05:39.126Z" to match one of "2018-06-20T16:24:29.022Z"

1 spec, 1 failure
Finished in 163.33 seconds`

In the json, testmybot saved the timestamp for the image. When I am executing the test command, I am obviously getting an error.

Do you have any way to get around this problem ?

Thank you kindly,
