Using absolute_msec requires a 64-bit division operation every time we calculate it, which gets expensive on 32-bit architectures. Instead, just use the lazy "monotime_coarse_get()" operation, and don't convert to milliseconds until we absolutely must. In this case, it seemed fine to use a full monotime_coarse_t rather than a truncated "stamp" as we did to solve this problem for the timerstamps in buf_t and packed_cell_t: There are vastly more cells and buffer chunks than there are channels, and using 16 bytes per channel in the worst case is not a big deal. There are still more millisecond operations here than strictly necessary; let's see any divisions show up in profiles.
Tor protects your privacy on the internet by hiding the connection
between your Internet address and the services you use. We believe Tor
is reasonably secure, but please ensure you read the instructions and
configure it properly.
To build Tor from source:
./configure && make && make install
To build Tor from a just-cloned git repository:
sh autogen.sh && ./configure && make && make install
