If you have GNU date (accepts -d), this should do it.
Convert date+time to epoch time using %s format (seconds past epoch date).
Once you have the date+time as epoch time you can navigate forwards and backwards by just adding or subtracting the number of secs required (eg 3600 for 1 hour).
Use the GNU -d @<epochsecs> parameter to convert back to the display format.
