    "Html": "<p>Hi,</p>\r\n<p>I am using the library 1.8.4.5 on my Windows CE 6.0 device. At the moment I am struggling with the following problem: All files which have been successfully extracted have the actual time (time of extraction)&nbsp;set as the Last Modified time.<br><br>In my source code I&nbsp;have checked the properties LastModified and Mtime of an affected ZIP entry during the&nbsp;<span style=\"font-size:x-small\">Extracting_BeforeExtractEntry event. At this time</span>&nbsp;Mtime is &quot;12:00:00 AM&quot; and LastModified is &quot;4/9/2009 12:31:32 PM&quot;.&nbsp; The property LastModified contains the correct DOS Last Modified time. The content of Mtime is not clear to me. I thought Mtime should be empty (if no NTFS time was available) or the same as LastModified? So the property LastModified contains the correct time, however DoNetZip does not use it.<br><br>During my tests I have found this topic:&nbsp; <span id=\"ctl00_ctl00_MasterContent_Content_TitleLabel\"><a title=\"SetLastWriteTime fails on Compact Framework\" href=\"http://dotnetzip.codeplex.com/WorkItem/View.aspx?WorkItemId=7944\">SetLastWriteTime fails on Compact Framework</a>. It seems to me that my problem is maybe related to this issue.</span><br><br>I apologize if this question has been answered but I have not been able to find any information on this error.<br><br>Regards Peter</p>",
