/*
* safetime.h --
*
* This header file defines wrappers so that we use the
* 64-bit versions of the C time calls. This file is
* temporary until we switch to a newer version of
* Visual Studio that uses the 64-bit verisions by default.
*
* In Windows, the user is allowed to set the time past the
* 32-bit overflow date (in 2038), which can cause crashes
* and security problems. In Linux, the time can't be set
* to overflow, so we do nothing.
*
* NB: We do not know if one can set the time past 2038 in
* 64-bit versions of Linux, and, if so, what happens when
* one does. This requires further investigation sometime
* in the future.
*
* The stat types and functions must be defined manually,
* since they contain time_ts, and we can't use the macro
* trick, since the struct stat and the function stat have
* the same 32 bit name (but different 64 bit names).
