Inclusion of "time" field in JSON even if unwanted.

[nakedsnake888]

What happened: Hi, I just was wondering if sending the "time" field could be avoided since apparently setting the time_key doesn't remove the key itself (and this is wanted behaviour from what I've seen. Any other way I could remove that time field? Your help would be very appreciated, thanks.

What you expected to happen:
I want to remove the time field since I don't need it in my json body (I have another field called TIMESTAMP anyway I think).
How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?: Plugin version 1.3.1
