Following an order from Chief Judge J. Carlisle Overstreet, which set the window for execution for next week, the Georgia Department of Corrections set the execution time for 7 p.m. Tuesday at the state prison in Jackson.
Mr. McClain, 42, was sentenced to die for murdering 28-year-old Kevin Brown during a robbery of a Domino's Pizza store Nov. 20, 1994.
Mr. McClain's attorneys have asked the U.S. Supreme Court to reconsider its denial of his request for a hearing, and the attorneys have requested a stay of execution, District Attorney Ashley Wright said.
Unless the stay is granted, the state will proceed with the execution.
Mr. McClain's attorneys argue that a pending Alabama death penalty case could "alter the legal prism" through which his case is viewed.
The Alabama case, set to be heard in November, centers on whether a new trial should be granted if a trial lawyer didn't raise certain objections during the penalty phase of a trial. The case prompted the court last month to delay the execution of a Texas man.
The State Board of Pardons and Paroles has set aside Friday morning to allow advocates for Mr. McClain to meet with the board members, said Tracy Master, a board adviser.
Clemency is possible if three of the five board members vote to grant it.
