It's been talked about before, but this calls for a reminder: attempting to convert a date prior to Jan 1, 
1970 to "seconds" returns "invalid date" instead of a number in Windows. Don't do this if you are going to 
need this to work in Windows! Under Windows, you need to subtract the birthyear from the current year and 
determine if the current month/day is later than the birth month/day and subtract one year if necessary. 
Conveniently, this methods does work on all platforms. 

Best,

Warren
