  * bugfix: require bugfixed versions of Date::JD and Time::UTC (for
    $SIG{__DIE__} handling)
  * in Time::TT::OffsetKnot, be more stringent in parsing supplied data
  * in Time::TT::tt_realisation(), more cleanly reject "bipmNN"
    realisation names that include non-ASCII digits
  * be more stringent in parsing time scale data files
  * regularise LWP version checking code
  * use simpler "parent" pragma in place of "base"
  * in Time::TT::Agencies documentation, note new agencies BY, EIM,
    INTI, KIM, KZ, LV, NRL, SIQ, SMD, UA, VMI
  * in Time::TT::Agencies documentation, note renamings NMC->BIM,
    ZMDM->DMDM, IGMA->IGNA, OMH->MKEH, CSIR->ZA
  * document standard Time::TT::Realisation methods in
    Time::TT::InterpolatingRealisation
  * document standard Math::Interpolator::Knot methods in
    Time::TT::OffsetKnot
  * in documentation, use "^" instead of "**" to signify exponentiation
  * in Time::TT::OffsetKnot, abandon use of the "fields" module
  * POD markup fix
  * use full stricture in test suite
  * test POD syntax and coverage, and rename some internal functions to
    satisfy the coverage test
  * drop prototypes from method subs (where the prototypes have no effect)
  * build with Module::Build instead of ExtUtils::MakeMaker
  * complete dependency list
  * include signature in distribution
  * in documentation, separate "license" section from "copyright" section
  * check for required Perl version at runtime
version 0.003; 2007-02-05
  * new functions tt_instant_to_jepoch() and tt_jepoch_to_instant()
    to handle interconversion with Julian epochs
  * in documentation, reference Time::TCG
  * test explicitly for correct class of result
version 0.002; 2007-01-21
  * in Time::TT::OffsetKnot, avoid "my __PACKAGE__", for compatibility
    with perl v5.6
  * typo fix in Time::TT::Agencies documentation
version 0.001; 2006-08-03
  * list exact required modules in Makefile.PL
  * use "=> 0" instead of "=> undef" in unversioned dependencies in
    Makefile.PL
  * don't include underscore in string version of module version numbers
    in Makefile.PL
  * use "warnings" and "strict" pragmas in all modules
  * documentation clarifications
