[ruby-core:47554] [ruby-trunk - Bug #7031] Date::mjd_to_jd disappeared

Issue #7031 has been updated by david_macmahon (David MacMahon).


FWIW, they were part of 1.8.7:  

http://www.ruby-doc.org/stdlib-1.8.7/libdoc/date/rdoc/Date.html#method-c-mjd_to_jd

Comparing the docs for 1.8.7 and 1.9.3, it looks like all of the ::*_to_* conversion methods were dropped.

## Ruby 1.8.7
$ irb -f -r date
irb(main):001:0> RUBY_VERSION
=> "1.8.7"
irb(main):002:0> Date.methods.grep /_to_/
=> ["jd_to_mjd", "civil_to_jd", "day_fraction_to_time", "jd_to_commercial", "ld_to_jd", "jd_to_ordinal", "time_to_day_fraction", "jd_to_civil", "zone_to_diff", "jd_to_ld", "amjd_to_ajd", "ajd_to_jd", "jd_to_wday", "ajd_to_amjd", "commercial_to_jd", "mjd_to_jd", "ordinal_to_jd", "jd_to_ajd"]

## Ruby 1.9.3
$ irb -f -r date
irb(main):001:0> RUBY_VERSION
=> "1.9.3"
irb(main):002:0> Date.methods.grep /_to_/
=> [:respond_to_missing?]

 I've migrated almost all of my Ruby code from Ruby 1.8 to 1.9 (finally!).  Most things went pretty smoothly, but I recently came across a script of mine that uses Date::mjd_to_jd.  This method, along with several other Date methods, seems to have disappeared from Ruby as of r31668.  I didn't see any discussion of these methods in the commit logs nor could I find anything about them on the web or ruby mailing list archives.  Are there replacement methods for these that I should be using instead?  Was there a reason for removing these methods that I should be aware of before monkey patching them back in?  Am I missing something?
 
 Thanks,
 Dave
