[Feature Request] Automatically convert timestamps to formatted timestamps

Like explained in: https://discord.com/developers/docs/reference#message-formatting-timestamp-styles, you can send timestamps that automatically convert to your timezone using the <t:timestamp> syntax. The timestamp needs to be a unix timestamp (seconds after 1970), which is often a bit of a hastle to make. Often you need some other website to make the timestamp for you, which takes some time and effort. 

It would be really nice if Discord had an option or suggestion to automatically convert timestamps like 16:20 to <t:1661870400:t> in the timezone of the user typing the message. That would really help confusion about timezones as everyone would easily see the time in their timezone. 

It would be even better if the different formats were also accepted. Like 20/04/2021 turning into <t:1618929600:d> like the Short Date format.
