What you have said doesn't make sense:

| their entries in table2, sorted descending by the table2's timestamp
| however to get the "last".
Did you miss some words out? Please rephrase this as it currently does not
make sense??

| ORDER BY statement as I am not getting the last entry's date.
How would and ORDER BY prevent you getting a date? All the order by would do
is set the order in which the results are presented, it would not affect
which results you would see.
