The following is an example of an NLF load file - where the date is set in Server format:
Server Format - specific to using the server, where DEVDateTime is scoped by DateTimeType YYYY/mm/dd-hh:mm:ss:sss:
.DEVTag
..Name|DEVTAG-001
..Description|
..ContainerID|
..DEVProp_EngWriteOthersRead|False
..DevUnitForTag|
..DEVProp_EngOnly|False
..SPFNeedsIndexing|True
..DEVTagCategory|{239410D8-4DDC-41B2-9116-0F9856921CBE}
..DEVDateTime|2012/01/27-16:41:54:192
Local Format - this is specific to your local computer, so the date format would be dd:mm:yy or mm:dd:yy. If no time is specified, the local date is converted to the server format in the load file, and the time string 00:00:00 (indicating midnight local time) is appended.
