[MISP] Timestamp issue

[NiQuintin]

Description

Entities and containers ingested by the MISP connector can have incorrectly adjusted timestamps. Sometimes the original creation date of the entity in OCTI is prior to the creation of the report itself in the source.

Environment

OpenCTI version: 6.4.4

Reproducible Steps

Steps to create the smallest reproducible scenario:

1. Deploying MISP connector for ingestion of reports (for example),
2. Comparing in the platform the Original creation date and the MISP event's date (+publication date of the source)

Expected Output

The entity's original creation date in the platform corresponds to the date of the ingested MISP event.

Actual Output

The original creation date may be prior to the publication of the report in the source.

Think it's not linked to the connector but the platform: OpenCTI-Platform/opencti#9357
