XmlFileErrorLog: filename timestamp does not match actual time of error

[GoogleCodeExporter]

When an Error object is created (Error.cs constructor), it stores the time
in its _time field.
However, when XmlFileErrorLog (XmlFileErrorLog.cs) actually logs that
error, it makes another call to DateTime object and converts it to string
in order to use in the filename as a time-stamp.

This behavior sometimes causes the seconds fraction in the filename to be
different that the one in the error object's time property, due to time
difference between the two calls (the one in the Error's constructor, and
the one in the XmlFileErrorLog's Log method).

In XmlFileErrorLog's Log method, using the error's time property to create
a time-stamp should fix the issue. Like so ;

Instead of : var timeStamp = DateTime.UtcNow.ToString("yyyy-MM-ddHHmmssZ",
CultureInfo.InvariantCulture);
This would be better : var timeStamp =
error.Time.ToUniversalTime().ToString("yyyy-MM-ddHHmmssZ",
CultureInfo.InvariantCulture);

Demonstration of fix:

IronPython 2.6 (2.6.10920.0) on .NET 2.0.50727.4200
Type "help", "copyright", "credits" or "license" for more information.
>>> import clr
>>> clr.AddReference('Elmah')
>>> from System import DateTime, ApplicationException
>>> from System.IO import Directory
>>> from Elmah import Error, XmlFileErrorLog
>>> log = XmlFileErrorLog(r'C:\errors')
>>> error = Error(ApplicationException())
>>> error.Time = DateTime(2010, 1, 1, 12, 0, 0)
>>> log.Log(error)
'93061650-58ff-4d7d-91de-ca97e555db8c'
>>> print '\n'.join(Directory.GetFiles(log.LogPath))
C:\errors\error-2010-01-01110000Z-93061650-58ff-4d7d-91de-ca97e555db8c.xml

The time embedded in the file is that which was set on the Error object's Time 
property.
