if is date data type, then i think time portion will be taken care of automatically with your update itself.

Try using select to_char(create_ts, 'ddmmyyyy hh24:mi') from table_name

In case create_ts is not a date but a varchar, try

Update table_name
set
create_ts = to_char(sysdate-3, 'ddmmyyyy hh24:mi:ss')
 where
staging_id in (XX1,XX2,XX3)
order by create_ts desc

create_ts will have to be large enough to hold the date string

Are you actually losing the time portion of the date in the column in the database, or is the tool you are using to display the values simply hiding the the time portion from you?

Please tell us:
1. the datatype of the "create_ts" column
2. which tool you use to view the results
3. your setting for NLS_DATE_FORMAT

What do you mean by "losing the timestamp associated with that ..."? The time portion is there, you may just need to have it displayed.
p.s. You don't use order by in an update statement

Update table_name
set
create_ts = current-timestamp - interval '3' days
 where
staging_id in (XX1,XX2,XX3);

what do you hope to acheive with the order clause ?
