(a) General Time Limitations. A petition to correct an illegal sentence may be filed at any time. No other petition shall be filed pursuant to this rule more than 5 years after rendition of the judgment or sentence sought to be attacked unless it alleges facts showing that the delay beyond said time was due to defendant's excusable neglect.
(b) Capital Causes; Petition. In cases in which the death penalty has been imposed, defendant's petition for post-conviction relief must be filed within thirty days of the denial of certiorari or other final action by the United States Supreme Court in respect of defendant's direct appeal.
