Oracle 11g ORA-01190: control file or data file 1 is from before the last RESETLOGS
Since you've done an open resetlogs, you've changed the incarnation and are now trying to restore to a previous incarnation.  From the Backup and Recovery User's Guide: 


  The procedure for DBPITR within the current incarnation is different
  from DBPITR to an SCN in a noncurrent incarnation. In the latter case,
  you must explicitly execute the RESET DATABASE to reset the database
  to the incarnation that was current at the target SCN. Also, you must
  restore a control file from the database incarnation containing the
  target SCN


After the above paragraph the manual goes on to detail the procedure, step by step.

It doesn't matter if you specify 'to time' or 'to scn'.  If you specify 'to time', rman will internally convert that to an SCN.
