Simulation virtual time values and global simulation resolution.
This class defines all the classic C++ addition/subtraction operators: +, -, +=, -=; and all the classic comparison operators: ==, !=, <, >, <=, >=. It is thus easy to add, substract, or compare Time objects.
For example:
You can also use the following non-member functions to manipulate any of these ns3::Time object:
This class also controls the resolution of the underlying time value. The resolution is the smallest representable time interval. The default resolution is nanoseconds.
To change the resolution, use SetResolution(). All Time objects created before the call to SetResolution() will be updated to the new resolution. This can only be done once! (Tracking each Time object uses 4 pointers. For speed, once we convert the existing instances we discard the recording data structure and stop tracking new instances, so we have no way to do a second conversion.)
If you increase the global resolution, you also implicitly decrease the range of your simulation. The global simulation time is stored in a 64 bit integer, whose interpretation will depend on the global resolution. Therefore the maximum duration of your simulation, if you use picoseconds, is 2^64 ps = 2^24 s = 7 months, whereas, had you used nanoseconds, you could have run for 584 years.

Record all instances of Time, so we can rescale them when the resolution changes.
We use a std::set so we can remove the record easily when ~Time() is called.
We don't use Ptr<Time>, because we would have to bloat every Time instance with SimpleRefCount<Time>.
Seems like this should be std::set< Time * const >, but Stack Overflow says otherwise, quoting the standard:
& sect;23.1/3 states that std::set key types must be assignable and copy constructable; clearly a const type will not be assignable.

We're called by Simulator::Run, which knows nothing about the mutex, so we need a critical section here.
It would seem natural to use this function at the end of ConvertTimes, but that function already has the mutex. Our SystemMutex throws a fatal error if we try to lock it more than once in the same thread (at least in the unix implementation), so calling this function from ConvertTimes is a bad idea.
Instead, we copy this body into ConvertTimes.

Record of outstanding Time objects which will need conversion when the resolution is set.
Use a classic static variable so we can check in Time ctors without a function call.
We'd really like to initialize this here, but we don't want to require C++0x, so we init in time.cc. To ensure that happens before first use, we add a call to StaticInit (below) to every compilation unit which includes nstime.h.
