Never surrender on a Thursday or Friday. Asssuming you have a bond lined up you won't get out until Monday at the earliest. Weekends don't count in calculating the time from arrest to arraignment which must be 48-72 hours generally.
In Texas, you get credit for all time you are sitting in jail waiting on a motion to revoke your probation except in some instances regarding state jail cases. Different courts handle their dockets in different ways. Most courts try to have the accused appear within 48 hours of arrest. Some courts have docekts just for MTR, just for discovery motions, just for trial, just for pleas, etc.
