Extension of 1-sample t-test to repeated measures?

If a repeated-measures ANOVA is an extension of a 2-sample t-test, what is the extension of a 1-sample t-test and how would it be coded in SAS?

More detail: I have paired community ecology data across a range of communities: a metric describing observed community structure and an 'expected' metric generated from a null model. Traditionally for this data one calculates observed-expected values and analyzes them with a 1-sample t-test (comparing the mean to a null hypothesis of zero). However, my communities are not independent (they were repeatedly sampled across time: 5 communities x 6 dates = 30 samples).

Thanks--
