There are TIME and TSIZ fields in the ID3 spec but Mp3tag writes to TXXX fields instead.
These fields are not listed in the help page list of supported fields
TIME
SIZE
ITUNESMEDIATYPE
TVEPISODE

These fields are out of alphabetical order in the help list

TIME and TSIZ frames are not supported by Mp3tag.

Thanks Dano,
I wonder why are Time and Size listed in the "Extended fields" menus then?
