I'm developing a bot and I want to a message to say "Account created today" or something like that (as it does when using timestamp property on embeds) instead of "Account created on 2020-09-02 12:22:47.893000"
The code I have now is this:

```
@client.event
async def on_member_join(member)
embed = discord.Embed(
    description=f":inbox_tray: <@{member.id}> joined.",
    colour=discord.colour.Color.dark_green(),

    timestamp=datetime.now()
)
embed.set_thumbnail(url=member.avatar_url)
embed.add_field(name='Account created:', value=member.created_at)

embed.set_footer(
    text=f'User Id: {member.id}')
await client.get_channel(logchannel).send(embed=embed)

```

Thanks in advance.
