Alarm with None time attribute returns an error

[PestusAtSAG]

Following alarm results in an exception:
alarm = Alarm(None, 'sag_DobotAlarm', None, deviceId, text, Alarm.Status.ACTIVE, Alarm.Severity.MAJOR)

File "C:\Users\APES\AppData\Local\Programs\Python\Python310\lib\site-packages\c8y_api\model\alarms.py", line 333, in create
super()._create(Alarm.to_full_json, *alarms)
File "C:\Users\APES\AppData\Local\Programs\Python\Python310\lib\site-packages\c8y_api\model_base.py", line 494, in _create
self.c8y.post(self.resource, json=jsonify_func(o), accept=None)
File "C:\Users\APES\AppData\Local\Programs\Python\Python310\lib\site-packages\c8y_api_base_api.py", line 190, in post
raise ValueError(f"Unable to perform POST request. Status: {r.status_code} Response:\n" + r.text)
ValueError: Unable to perform POST request. Status: 422 Response:
{"error":"undefined/validationError","message":"Following mandatory fields should be included: time","info":"https://www.cumulocity.com/guides/reference-guide/#a-name-error-reporting-a-error-reporting"}

Using now() is working fine:
alarm = Alarm(None, 'sag_DobotAlarm', datetime.now().isoformat(), deviceId, text, Alarm.Status.ACTIVE, Alarm.Severity.MAJOR)

Not an API error, because this is caused by Cumulocity backend. But it would be a nice feature to have without diverting from the API concept.

I've updated to API to accept time='now for both Event and Alarm. This is more explicit that leaving it blank and still handy enough I think.
This is part of version 1.2.
