Something like this:

struct tm tm;
time_t epoch;
strptime(your_formated_date, "%d/%m/%Y", &tm);
epoch = mktime(&tm);

strptime and mktime.

Be aware that timezone affects the answer, since a standard timestamp is seconds since 1970 UTC, not necessarily seconds since 1970 local time.

Also be aware that the epoch isn't guaranteed by the C++ standard to be 1970, although it is on common systems.
