Question

Convert a string to a date in C++

I have a date/time string in a standardized format (RFC 1123) that I would like to convert to a unix timestamp to compare it with another date/time.

I can convert a timestamp to a string by using strftime with the magic format string

"%a,%d %b %Y %H:%M:%S GMT"

The problem is, I need to do the inverse of this, and turn the formatted string back into a timestamp. What is the best way to do this?
