Fix default date used for time columns

When a time column is retrieved and converted to a Date object, SQL
Server's default date of 1900-1-1 is substituted for the missing
components since time columns don't have a date.

However, the constants being used for this were erroneously using JS
default of 0 as the month rather than 1, the SQL Server default. This
affected the conversion process and caused certain dates to be
returned incorrectly.
