The metrics and font map entries for the Mathtime fonts are available
in teTeX. The type1 files containing the actual fonts are not free and
cannot be distributed with teTeX. Therefore, the default setup of teTeX
activates the free Belleek fonts which are a good replacement for the
Mathtime fonts (no Plus). To use the commercial Mathtime / Mathtime Plus
fonts, a few extra steps are needed:

=========================================================================
  If you have purchased just the Mathtime fonts, you should:
=========================================================================

1a) copy
      mtex.pfb mtsy.pfb rmtmi.pfb
    into a directory named type1/yandy/mathtime inside your local
    texmf tree and run the command
      texhash

    Verify, that kpsewhich can find your files, e.g.
      kpsewhich mtex.pfb

1b) run the commands
      updmap --disable mt-belleek.map --nomkmap
      updmap --enable Map mt-yy.map

=========================================================================
  If you have purchased the Mathtime and Mathtime Plus fonts, you should:
=========================================================================

2a) copy
      mtex.pfb mtsy.pfb rmtmi.pfb
    into a directory named type1/yandy/mathtime and copy
      mtexb.pfb mtexh.pfb mtgu.pfb mtgub.pfb mtls.pfb mtlsb.pfb mtms.pfb
      mtmsb.pfb mtsyb.pfb mtsyh.pfb mtsyn.pfb rmtmib.pfb rmtmih.pfb
      rmtmub.pfb rmtmuh.pfb
    into a directory named type1/yandy/mathplus inside your local texmf
    tree and run the command
      texhash

    Verify, that kpsewhich can find your files, e.g.
      kpsewhich mtex.pfb

2b) run the commands
      updmap --disable mt-belleek.map --nomkmap
      updmap --enable Map mt-yy.map --nomkmap
      updmap --enable Map mt-plus.map

2c) update the three my*.fd files contained in tex/latex/mathtime. For
    this, you need the files mathtime.dtx, mathtime.ins and mtfonts.fdd
    from the docstrip sources of the mathtime package (e.g. contained
    in the texmfsrc tarball in teTeX or on CTAN as part of the psnfssx
    bundle).

    Make sure, that in mathtime.ins, the line
      \def\mtplus{}
    is disabled by a % character, then run
      latex mathtime.ins

    Copy the files my1mtt.fd my2mtt.fd my3mtt.fd to the directory
      tex/latex/mathtime
    of your local texmf tree and run
      texhash
