A lot of issues with <tg-time>

[jacklul]

Incredibly inconsistent errors and issues:

<tg-time unix="1873542818" format="dt">2029-05-15 12:33:38 UTC</tg-time> works

<tg-time unix="1873629218" format="dt">2029-05-16 12:33:38 UTC</tg-time> causes Bad Request: ENTITY_DATE_INVALID

<tg-time unix="1897130018" format="dt">2030-02-12 12:33:38 UTC</tg-time> causes Bad Request: ENTITY_DATE_INVALID

<tg-time unix="2378550818" format="dt">2045-05-16 12:33:38 UTC</tg-time> works but does not get formatted

<tg-time unix="3822122018" format="dt">2091-02-12 12:33:38 UTC</tg-time> works but does not get formatted

You can't use Unix timestamp that big.

You can't use Unix timestamp that big.

I see no information on this in the "Date-time entity formatting" section, can you direct me to where should I look?
Makes no sense to throw ENTITY_DATE_INVALID error if even bigger timestamps work without being formatted.
Basically this makes this feature useless for larger scale usage with dates way more into the future.

Anything beyond signed int32 definitely can't work right now.
