bug#68064: Date addition error with “day Monthname” versus “Monthname day”

[Larry Ploetz]

It seems like there might be a problem with date addition when the base 
date is specified as “day Monthname” instead of “Monthname day”, where 
the offset is being interpreted as an absolute year value. This may be 
locale-specific.
