SerialDate MINIMUM_YEAR_SUPPORTED question

[david.gilbert]

It probably wouldn't be hard to make SerialDate go further back in time, just by using negative values. The first problem you'd run into is how to handle the screwy dates in the 1700's when the calendars changed around, but then you're only looking to support dates from the 1800's so that wouldn't matter. I'll probably take a look at this in the next week or two, because it is a dumb limitation.

Would be great if you could have a look at it. I'll get the sources and play around with SerialDate as well, maybe I can provide a patch.

Thanks,

We too are seeing the same problem. Basically if you create a Millisecond object with an older date you get the problem:

The 'year' argument must be in range 1900 to 9999.
java.lang.IllegalArgumentException: The 'year' argument must be in range 1900 to 9999.

I believe we are running with the latest release from April 20, 2009

Any ideas for a workaround?
