Does the time taken to process a sample have an effect on quality of sequencing?

The accuracy of Sequencing by different machines is measured in Phreds. Is this Phred value a function of the machine itself? Of course an old and poorly stored sample may affect the quality of the reads, but does the sample also affect the 'phred' score? Is there a way to determine the average Phred Score from your FASTQ file? Is there a cut off value below which Dante Labs asks for repeat sampling?
