Log:
Move time cast to SymbolFileDWARFDebugMap
When trying to fix the bots we expected that the cast would be needed in
different places. Ultimately it turned out only the
SymbolFileDWARFDebugMap was affected so, as Pavel correctly notes, it
makes more sense to do the cast just there instead of in teh FS.
