This PR adds proper start time while adding card details (stripe) to eliminate the endlessly showing loading icon and showing this traceback:

@anup-dh date is not an mandatory field for get_timestamp function in develop frappe version atleast.

https://github.com/frappe/frappe/blob/faf07ffe95e44e77fce727579cee042b59ad5439/frappe/utils/data.py#L376-L380

Based on git blame, the behaviour of the function hasn't changed in 2yrs.

Hmm. but what triggered the error then ?

Check your frappe version and the get_timestamp function source code. Might be you have some modification locally.
