Having two different date systems with different base dates side-by-side in the same standard document format makes no sense. Rather, it is appropriate to fix a single base date. Applications which use a different base date can convert from the date representation used in the standard document format to the application’s preferred date representation, and vice versa.

Delete all references to the "1904 base date system".

Proposed Disposition of DIS 29500 Comment GR-0008 (Modified: 2008-01-11) Most of the concerns raised by this comment have been addressed in our single response to the following NB comments: CH-0006, CH-0017, CO-0035, CO-0154, CZ-0009, DE-0031, FI-0013, FR-0182, FR-0351, GB-0300, GB-0304, GB-0363, GR-0003, GR-0006, IE-0002, IN-0007, IN-0057, IN-0061, IN-0080, IR-0001, KE-0054, MX-0005, MY-0003, PE-0002, PT-0085, US-0130, UY-0003, VE-0011, and VE-0060. Regarding the requests that we adopt a single date base, we do not see this as a viable option given the corpus of existing binary documents requiring support for the existing 1900 and 1904 date bases. Additionally, we believe that our single response noted above creates a better default date base, allowing a larger range of dates than the existing 1900 or 1904 date base and better compatibility with the existing corpus of binary documents.
