set timestamp to bootstrap datetimepicker

I'm working with Laravel 5, in a view I'm using the bootstrap datetimepicker I have a timestamp saved in the database, and when the user load that view I want to preload that date in the datetimepicker. As I read there's a method datepicker('setDate',startDate); to set the date, but I need to assign the value that is accesible trought PHP, as I am using blade my timestamp is accesible with:

{{$contract->myTimestamp}}

So, I can I do it?
