  We introduce the Mathematica package SummerTime for arbitrary-precision
computation of sums appearing in the results of DRA method. So far these
results include the following families of the integrals: 3-loop onshell
massless vertices, 3-loop onshell mass operator type integrals, 4-loop QED-type
tadpoles, 4-loop massless propagators. The package can be used for
high-precision numerical computation of the expansion coefficients of the
integrals from the above families around arbitrary space-time dimension. In
addition, this package can also be used for calculation of multiple zeta
values, harmonic polylogarithms and other transcendental numbers expressed in
terms of nested sums with factorized summand.
