Calls created through API without start time

Hi,

I am trying to set calls through API.
Using V8 APi and SuiteCRM Version 7.11.13
New records are created with all data that passed, except the date_start and date_end, that are saved empty.
What could be a problem?
I am formatting the date time to ISO format like this:

$datetime = new DateTime('2020-08-02 14:00');
$converted_call_time = $datetime->format('c');

This code produces formatted date like this:
2020-08-02T14:00:00+03:00
And this is a value that passed to API.

Any help will be appreciated.

Hi,
did you try something like Y-m-d H:i:s (e.g. 2019-09-12 06:47:00)?
