How Can I Know When A User Joined Discord In Discord.py (discord Join Date, Not Server)

I know that to know when a user joined your server, you can: member.joined_at will work out.

Solution 1:

Use User.created_at:

@client.command()
async def userinfo(ctx, member: discord.Member):
    created_at = member.created_at.strftime("%b %d, %Y")
    await ctx.send(created_at)
