I couldn't find an obvious system utility, so I knocked the following
bit of code together.
/*
        timeconv.c
        Convert seconds to time.
*/
#include <stdio.h>
#include <time.h>
int main(int argc,char **argv)
{
        time_t  t;
        register int i=0;
        while(--argc){
                i++;
                t=atol(argv[i]);
                printf("%s",ctime(&t));
        }
        return 0;
}
