[ome-users] ZVI Acquisition Date Formatting

[Joseph Padfield]

Hi,

I am trying to extract the "Acquisition Date" from a large set of Zeiss 
Vision Image (ZVI) files using the "bftools" command line tools. I can 
get the field without any problem but I can not find out how to convert 
the returned integer into a formatted date. Hopefully I have just missed 
something simple.

When I open an individual test file in the official AxioVision LE 
software the following data can be displayed:
Acquisition date: 19/04/2011 16:10:42
Date: 19/04/2011 13:48:35

But the only fields I can get via the bftools "showinf" function are:
Acquisition Date: 4675820074566218095
File Date: 4675820078182691028
(using showinf -omexml -nopix - nocore filename.zvi)

Is there a way of converting "4675820074566218095" to something like 
"19/04/2011 16:10:42" using any of the command lines tools or any other 
standard datetime conversion processes. The only information I can find 
is that the field should be stored as an "ISO 8601" date which is 
described as using a format like [YYYY]-[MM]-[DD]T[hh]:[mm]:[ss], but I 
can not find anything about a 19 digit integer.

I am using the command line tool "showinf" in linux:
Version: 4.4.1
VCS revision: fae9833
Build date: 19 July 2012

Thank you for any help.

Joe
