Pavlo on Does ThingSpeak MQTT support relative timestamp delta_t instead of absolute created_at just like in REST API

Hi, ThingSpeak's REST API declares support for relative timestamps in bulk updates (see https://www.mathworks.com/help/thingspeak/bulk-update-a-channel-feed-1.html). One just need to set delta_t field instead of created_at

Does anybody know if MQTT supports the same?

Spec does not mention it, but who knows, maybe TS has not yet updated it.
