Can a judge give you jail time for a warrant of arrest?

Your question requires an attorney consultation. It is not a simple question that can be answered on this type of forum. There are many factors that would need to be considered and evaluated. Since we do not have all the facts, it is impossible to give a completely accurate answers. Why is there an arrest warrant. What are you being charged with? I strongly suggest that you contact an experienced criminal defense attorney for a face-to-face consultation and give him/her all of the facts surrounding your situation. (S)he would then be in a better position to analyze your case and advise you of your options.

Absolutely. Which is why you should hire a lawyer to go to court to recall the warrant. A lawyer can do this without you present, so it is less risky for you.

You can be put in custody whenever you fail to show up to court (excluding infractions) and a warrant is issued. It is not the warrant itself but the charges for which you failed to appear that can cause you to be given jail time, although failing to appear at a court hearing can be charged as a separate offense. How much time, if any, depends on many factors, such as the whether the charge that generated the warrant was a felony or misdemeanor, the reasons for the failure to appear, the accused's criminal history, and a host of others. The best thing to do is to take care of the warrant by appearing in court, and if you're wise you will have a criminal defense attorney help you.
