Description

Members who join a guild voice channel via a guest invite have joined_at set to null, which is either a bug or a silent breaking change as it goes against what's documented for the Guild Member Object.

First mention of this (or an extremely similar) issue seem to be #3152, then it was mentioned in this pr

Steps to Reproduce

• create a guest invite for a voice channel
• join via the invite from an account that is not a member of the guild
• the VOICE_STATE_UPDATE will have "joined_at": null on the member object

Expected Behavior

joined_at having some sort of value, probably the timestamp when user joined the guild/voice channel

Current Behavior

"joined_at": null
