What you have there is the number of seconds since midnight Jan 1 1970. This is known as epoch time. To convert you can use the localtime function, this returns, an array of the date elements by default, however if called in a scalar context it will return a time string, you can force scalar context with the scalar function ot by assigning to a scalar variable

Alternatively read my sig ;)

Incidental note, 198768745 represents Mon Apr 19 14:32:25 1976, so either

• You typed in some random digits rather than the content of (stat $file)[9]
• You're running a UnixTSS box
• Or the figure came from somewhere else
