RMAN Point-in-time recovery

Metalink Docid Note:370500.1

RMAN> run {
set until time "to_date('10.07.07 17:23:36','dd.mm.yy hh24:mi:ss')";
restore database;
recover database;
}

This shit is not working if you don't set the NLS_LANG environment variable. It fails with an error like:
ORA-01841: (full) year must be between -4713 and +9999, and not be 0

Also note how is the date parameter passed to the set until time. it's in double-quotes on some reason.
