commit 3ed1c7616df3b828f50165a0b68b5c16a4d17480
Author: John Ralls <jralls at ceridwen.us>
Date:   Sun Dec 11 17:21:28 2016 -0800

    Remove QIF importer error “Dates earlier than 1970 are not supported”.
    
    Because they are. The parser can’t figure out years earlier than 1930,
    but that’s not really a major concern.

commit 54beffd9367221402ff09fb8493e8112fe637732
Author: John Ralls <jralls at ceridwen.us>
Date:   Sun Dec 11 16:32:15 2016 -0800

    Bug 685329 - Crashes on non-existent date
    
    Log an error instead of crashing. The transaction will be imported with
    today’s date.

commit 78b41f7ac14d1a19f588e1d9ef6cb4a10bb276b7
Author: John Ralls <jralls at ceridwen.us>
Date:   Sun Dec 11 15:23:55 2016 -0800

    Bug 772369 - Replace use of guile's internal date/time functions
    
    with our own implementation of gnc-date.
