We get the following warnings with clang.
> ipc/chromium/src/base/time_posix.cc:103:57: error: overflow in expression; result is 0 with type 'long' [-Werror,-Winteger-overflow]
> ipc/chromium/src/base/time_posix.cc:106:58: error: overflow in expression; result is -1000 with type 'long' [-Werror,-Winteger-overflow]
This is a genuine bug. The upstream code in Chromium has changed (commit
2a278516943eee02e0206506a4b907fc0b55f27b) and this patch changes our code to be
similar. I did tests and confirmed that instead of getting 0 or -1 for
|milliseconds|, we now get -2147483648000 or 2147483647999, which is much
better.
