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, subtract, 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 representation. 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 maximum simulation duration. The global simulation time is stored in a 64 bit integer whose interpretation will depend on the global resolution. Therefore the maximum possible 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. The mutex can not be locked more than once in the same thread, so calling this function from ConvertTimes is a bad idea.
Instead, we copy this body into ConvertTimes.

This is the same as the "normal" C++ integer division, which truncates (discarding any remainder).
As usual, if ta, and tb are both Times

| [in] | rhs | The second value |
lhs / rhs.

Scale a Time by a numeric value.
This overload handles the case where the scale value comes before the Time value. It swaps the arguments so that the Time argument comes first and calls the appropriate overload of operator*
| T | Arithmetic data type (int, long, float, etc.) |
| [in] | lhs | The scale value |

Exact division, returning a dimensionless fixed point number.
This can be truncated to integer, or converted to double (with loss of precision). Assuming ta and tb are Times:
| [in] | lhs | The first value |
| [in] | rhs | The second value |

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.
