Try the following line in your GLM syntax:
/EMMEANS = TABLES (time*group) COMPARE(group)
You can also add a ADJ() clause to the end of that line if you want to
adjust the significance values of the 3 individual tests to account for
multiple testing - options are LSD (no adjustment), BONFERRONI and SIDAK.
