I got the solution..!

a=55
export a
perl -e 'use POSIX qw(strftime); print strftime "%a %b %e %H:%M:%S %Y",localtime(time()+ 3600*24*$ENV{a});'

I have used perl to add 55 days to the current local time on the server.

Thanks..!

How about:

now=$(date +%s)
new=$((now + 55*86400))
date -r $new

With GNU date:

date -d @$new

-r is not recognized by my AIX..! `date: Not a recognized flag: r` `Usage: date [-u] [+"Field Descriptors"]` – Rohith May 18 '17 at 04:13
How about `date -d @$new`? – codeforester May 18 '17 at 04:44
Download GNU date and use `date -d @$new`. – codeforester May 18 '17 at 04:50

GNU is not enabled. – Rohith May 18 '17 at 05:28
with gnu date `date -d "55 days"` is all that's needed. but gnu date seems unavailable in this problem. – Jasen May 18 '17 at 05:31
