Unable to create coupon - error

[chainsaw1968]

Hi,
Currently running

Joomla! 3.8.2
VM: 3.2.6
PHP 5.6.32

I'm trying to create a coupon but keep getting the below error. Any ideas how to resolver this?

"An error has occurred.
0 DateTime::__construct(): Failed to parse time string (1515076797) at position 7 (7): Unexpected character"

Seeing the same problem and error message with coupon creation:

Joomla 3.82
VM 3.2.6
PHP 7.0
