Submit an Implementation report based on a nightly-unstable test suite: possible?

Peter,

I've read

http://lists.w3.org/Archives/Public/public-css-testsuite/2010Aug/0020.html

https://wiki.csswg.org/test/implementation-report

I would be ready and interested to enter test results of Prince 10 rev 3 
for the CSS3 Writing Modes test suite *nightly-unstable* build and 
submit an implementation report.

1- Is this possible?

2- If so, then what would be the DATESTAMP:
# http://test.csswg.org/suites/css-writing-modes-3_dev/DATESTAMP/

3-
When a test line has many characters in its 2nd (middle) column (in the 
column between testname and result), what does it mean?
eg

html/abs-pos-non-replaced-icb-vlr-003.htm	d3088b2113ff9dc88028dc89b4d030a83db59a2b	?
xhtml1/abs-pos-non-replaced-icb-vlr-003.xht	d3088b2113ff9dc88028dc89b4d030a83db59a2b	?
html/abs-pos-non-replaced-icb-vlr-005.htm	b959f5e9a4d09adc6784d74741b43ff0ac1ea0ca	?
xhtml1/abs-pos-non-replaced-icb-vlr-005.xht	b959f5e9a4d09adc6784d74741b43ff0ac1ea0ca	?

This comes from the implementation report template for the 
nightly-unstable test suite:
