Change time_pref to absolute in lvi file

[shane_s]

I have 8 analog inputs logging to an lvi file and would like to know how to change my time column to look similar to hh:mm:ss.sss. I think this simply involves changing the time_pref from relative to absolute but I do not know how to do this.

I tried the method described in How to set Time_pref to Absolute in *lvm files (Write to measurement File)  but this reduces my 8 inputs into one column when viewed in excel.

Thanks in advance!

The time column in an .LVM file is always relative time to reduce read/write time and file size.  The difference between relative and absolute shows up in the timestamp field in the header.  If you really want to change this, you can open the block diagram of the Express VI and dive in and change the appropriate VI.  Make sure you save the changed VI (and all parents) to a new location outside vi.lib to avoid breaking other code.  This is a fairly complex VI, but the appropriate VI should be relatively easy to find.  It is several layers in.  Let us know if you need more help.
