New issue 882 by tobias.kaes: OS::Ticks on windows wraps around every 70
minutes
http://code.google.com/p/v8/issues/detail?id=882
It's probably a minor issue because OS::Ticks is not used widely, but on
windows [1] it wraps around every 70 minutes instead of the usual 49 days.
Reason is that timeGetTime returns a DWORD, so the multiplication with 1000
is performed as 32-bit integer, causing overflow and truncation for values
greater than about 70 minutes. The correct way would be to cast *before*
multiplication as is done in platform-posix implementation of OS::Ticks [2].
