[R] Weird Excel Time Format

[Hasan Diwan]

I have a 10-column XLS file, with 2 date fields. As far as I can tell,
they were configured identically in Excel 2010. One of these fields
resembles "39406.577662037", whilst in Excel, it is shown as
"2007-11-20 13:42:20". Applying as.Date() with the default format
doesn't do it. Any ideas as to what format this is? Many thanks! -- H
