The first task seems to be to distinguish type 1 from type 2.
Searching for the first : (using strchr) and testing the next
character for space seems to work. Once you know it is a type 2, the
position of that : will tell you whether the time stamp is prefixed or
suffixed. Hopefully, this will get you started.
