The 3+1 dimensional string-parton model is used to calculate energy densities and temperatures of produced mesons during relativistic heavy-ion collisions. We compare maximum energy densities with the experimental estimates obtained from the Bjørken formula. Although the string-parton model reproduces transverse energy distributions, dET/dη, the dynamical energy densities of the produced mesons are three to four times smaller than estimates based on the Bjørken formula with a formation time of 1 fm/c. We discuss various time scales which contribute to this discrepancy and suggest a modified interpretation of the Bjørken formula.
