durante algún tiempo

= for a while, for some time, for some while, for some time to come, for days

Ex. The former library was in fact only used as a store for a while.

Ex. When I saw what he was up to, I drew back for a punch and hit him so hard on the nose that he fell on his back and lay there for some time, so that his wife stood over him and cried out 'Mercy! You've done my husband in!'.

Ex. For some while there have been calls for an abbreviated version of AACR, for small libraries and for non-cataloguers.

Ex. The traditional role of libraries and librarians as handlers of pre-packaged information will still be relevant in most organisations for some time to come.

Ex. Republicans have been tripping over each other for days trying to get their stories straight on who knew what and when.
