> A row can have multiple cells, and each cell can have a different timestamp.  The get
command in the shell demonstrates that cells are being stored with different timestamps:
> {code}
> hbase(main):008:0> get 'table1', 'row2'  
> COLUMN                       CELL 
>  fam1:letters                timestamp=1215707612949, value=def 
>  fam1:numbers                timestamp=1215707629064, value=123 
>  fam2:letters                timestamp=1215711498969, value=abc 
> 3 row(s) in 0.0100 seconds
> {code}
> However, using the scanners to retrieve these cells shows that they all have the same
timestamp:
> {code}
> hbase(main):009:0> scan 'table1'  
> ROW                          COLUMN+CELL
>  row2                        column=fam1:letters, timestamp=1215711498969, value=def

>  row2                        column=fam1:numbers, timestamp=1215711498969, value=123

>  row2                        column=fam2:letters, timestamp=1215711498969, value=abc

> 3 row(s) in 0.0600 seconds
> {code}
> The scanners are losing timestamp information somewhere along the line.
