Epoch date to YYYY/MM/DD or MM/DD/YYYY

I've seen a lot of posts on this and have tried the following:

 echo 1257000000| perl -e '($d,$m,$y)=(localtime(time-86400))[3..5];$m+=1;$y+=1900;printf "$y/$m/$d\n";'

But I am unable to convert a past Epoch date into a format such as YYYY/MM/DD or MM/DD/YYYY.

I am using bash and don't know much about perl. I can convert the current date, but nothing from the past. Unix gurus, any ideas as to what I might be doing wrong would be very greatly appreciated as I've spent a lot of time googling and reading and am unable to find any code to do this. I have been able to express current epoch time in various formats, but again, nothing from the past.

date -d @1257000000 +"%Y/%m/%d"

# 3  
Illegal option on date -d

This is great. But I don't have the ability to run date -d. The -d option is not supported. Any other suggestions?

date -d
date: illegal option -- d
