Win32_ReliabilityRecords Class

The Win32_ReliabilityRecords class was introduced with Windows 7. It contains information from the Windows Event Log related to system reliability.

The most interesting properties are the Message and the TimeGenerated

£> Get-WmiObject -class win32_reliabilityRecords | select -First 1 | fl Message, TimeGenerated

Message       : Installation Successful: Windows successfully installed the following update: Definition Update for  Windows Defender – KB2267602 (Definition 1.207.1367.0)
TimeGenerated : 20150929170914.620000-000

Notice the usual delightful date format on TimeGenerated

Easiest way to resolve this and get sensibly formatted date is to use the CIM cmdlets

£> Get-CimInstance -ClassName win32_reliabilityRecords | select -First 1 | fl Message, TimeGenerated

TimeGenerated : 29/09/2015 18:09:14

Now you have a date you can read easily.
