The two Guinness SHC quarter-finals which are due to be played in the Semple Stadium in Thurles on 22 July have been brought forward by an hour.
The tie between defending champions Cork and Limerick, which was originally scheduled to take place at 5.15pm, will now take place at 4.15pm.
The second quarter-final between Galway and Kilkenny will begin at 6pm rather than 7pm.
