  ctime()

  NAME

    ctime(), ctime_r() - transform binary date and time value to ASCII

  SYNOPSIS

    #include 
    #include 

    char * ctime (const time_t *clock)
    char * ctime_r (const time_t *clock, char *buf)

  DESCRIPTION

    The function ctime(3) function takes as an argument a time value
    representing the time in seconds since the Epoch (00:00:00 UTC, January 1,
    1970; see time(2)).

    The ctime(3) function adjusts the time value for the current time zone and
    returns a pointer to a 26-character string of the form:

    Thu Nov 24 18:22:48 1986\n\0

    All the fields have constant width.

    The reentrant ctime_r(3) function converts the calendar time referenced by
    clock to local time in exactly the same form as ctime(), puts the string
    into the array identified by buf (which must be at least 26 bytes in
    size), and returns buf.
