 Brian:

 Would it be okay if I changed {{{flogtool dump}}} and {{{flogtool web-
 viewer}}} to use the ISO 8601'ish, UTC, format that we earlier agreed and
 and that is implemented in

 http://allmydata.org/trac/tahoe/browser/src/allmydata/node.py#L29

 Currently I'm trying to match two logs, one of which is in dump format and
 one of which is in web-viewer format, and I can't find any matching
 timestamps.  The timestamps don't have any time zone information attached
 to them, which makes me think that they must be in UTC, but I'm not sure.

 Examples:

 from the dump:

 {{{
 oy2wi53k 1204167662.092443: helper: upload_chk query for SI
 fxka6q4pfenkvchyh2z4xkg5xa
 oy2wi53k 1204167662.0932679: doing a quick check+UEBfetch
 g5rdi5te 1204167662.096379: storage: slot_readv n5cbdwdbi3bec6opkmvnd6hhdm
 []
 g5rdi5te 1204167662.0970781: returning shares [1]
 }}}

 from the web-view:

 * 17:52:32 0.7390 ![26722]: !AssistedUploader starting
     * 17:52:32 0.7390 ![26724]: contacting helper..
     * 17:52:32 0.9500 ![26725]: helper says we need to upload
     * 17:52:33 0.5810 ![26731]: upload finished, building readcap

 !>>> pyutil.time_format.iso_utc(1204167662.092443)
 '2008-02-28_03:01:02.092443'

 So there's either a UTC-vs.-localtime problem here, or else I'm looking at
 logs from two different times.  Anyway, I'll stop posting my debugging
 notes in this ticket now.  ;-)

 assigning to Brian with the intent that he will answer the "yea/nay"
 question and assign it back to me
