Code:
One of the many methods is to temporarily adjust the timezone.
This example is for UK. The actual adjustment varies according to normal TZ.

#!/bin/ksh
echo "Yesterday  : $(TZ=GMT24BST;date)"
echo "Today       : $(date)"
echo "Tomorrow  : $(TZ=GMT-24BST;date)"

env TZ=GMT+24 date +%y%m%d
# assuming that your TZ is GMT
