strftime

Synopsis

strftime([format [,timestamp]]) {G}

Format timestamp according to format. Return the formatted string. The timestamp is a time-of-day value in seconds since midnight, January 1, 1970, UTC. The format string is similar to that of sprintf. If timestamp is omitted, it defaults to the current time. If format is omitted, it defaults to a value that produces output similar to that of the Unix date command. See the date entry in Chapter 3 for a list.
