 +====== Understanding file timestamps ======
 +
 +
 +Storage Made Easy uses [[http://​en.wikipedia.org/​wiki/​Coordinated_Universal_Time|UTC]] as an independent time format. This means that times for files are shown as UTC times and UTC is used to enable SME to understand whether a file needs to be updated or versioned.
 +
 +===== 1 File modified times =====

 +{{:/​timestamps:​steps:​sme_1_file_modified_times.png}}
 +
 +Hovering over the time field in the SME Web Browser shows 3 different times:\\ \\ Modified UTC - The last modified time for the file in UTC format\\ Modified Local- The last modified time for the file in the local time format, based on the browser locale settings\\ Create UTC - The date the file was created in UTC time.
 +
 +
 +===== 2 Uploading files from the web =====
 +
 +
 +
 +{{:/​timestamps:​steps:​sme_2_uploading_files_from.png}}
 +
 +If files are uploaded from the web File Manager then timestamps are only preserved if   firefox and chrome browser are used. These are the only two browsers that support file time preservation in upload (this is the case with any Cloud Storage vendor).  \\ \\ To be clear It is not possible to obtain local file stamps from web uploads for Safari and Internet Explorer and the time the file is uploaded is used for the creation and modified time of these files.\\
 +
 +
 +===== 3 Uploading files from the desktop =====
 +
 +
 +
 +{{:/​timestamps:​steps:​sme_3_uploading_files_from.png}}
 +
 +Files that are uploaded from a Mac, Windows or Linux Drive client, or via sync   should have the timestamps fully preserved, but converted to UTC (with local time also being shown in browser and on desktop).
 +
 +
 +===== 4 Uploading files over protocol adaptors =====
 +
 +
 +
 +{{:/​timestamps:​steps:​sme_4_uploading_files_over.png}}
 +
 +If files are uploaded over a SME CloudDav or CloudFTP protocol adaptor then timestamp preservation depends on the client tool used and whether it issues the command to change the file timestamp.\\ \\
