/* That is correct. # of seconds since 1/1/1970. */ Number of seconds since 1/1/1970 00:00:00 GMT. In perl, for example, we have a very simple line to convert Unix Timestamp into human-readable format: $ perl -e "print scalar localtime(0);" Wed Dec 31 21:00:00 1969 As I told, this is GMT based. So, here in Brazil we have GMT-3, then that's correct. CheerS
