The time can vary. If you are speaking of having your criminal record expunged of an offense - once the judge approves it (if he does) - court orders directing the expungement will go out to the various record-keeping agencies for them to act on it. Obviously it will not happen instantaneously, but within a few weeks to a month should probably be sufficient. Ask your attrorney, or even ask the judge, they should have a good handle on the timeframe.
It depends on what you mean by "clear your record." If you want to get a new trial, you will have to file an appeal of your trial with the state court of appeals. If you want an expunction of your record, it will involve filing a legal motion for the court to consider and it may or may not be successful - if you want a pardon, you will have to petition the governor's office. All these take their own time and none of them are swift.
Criminal records are not 'cleared'. A criminal record stays with one for life. It is one of the reasons not to commit a crime.
