2.0 Upgrade : Date preferences for "mailing" date type are wrong - causes CiviMail schedule date selector to not show HOURS selector

2.0 Upgrade (CRM/Upgrade/TwoZero/sql/others.mysql) has incorrect format value for the 'mailing' date type.

Current code:
(@domain_id, 'mailing', 'Date and time. Used for scheduling mailings.', 0, 1, 15, 'Y M d H i'),

Should be:
(@domain_id, 'mailing', 'Date and time. Used for scheduling mailings.', 0, 1, 15, 'Y M d h i A'),

NOTE: The 'custom' setting may also be incorrect as it has the same value and I don't think our Quickform date / time field supports that format:

(@domain_id, 'custom', 'Uses date range passed in by form field. Can pass in a posix date part parameter. Start and end offsets defined here are ignored.', 20, 20, 15, 'Y M d H i'),

Dave G suggests this may be an issue with the date preference setting, but as this has affected several installs (as reported in thread) it may be that the preference setting has originated from defaults in the DB.
