No our markup  shouldn't have no such ambiguity, you are right, It would 
require that "T" be marked up too...

<span class="duration time">
      <span class="h">1</span>:
      <span class="m">3</span>:
      <span class="s">42</span>

but again we would have the same issues that "m" is ambiguous, It really 
is a shame that microformats (as is semantic html) are all lower case or 
case insensitive, because if we were able to accept upper case values as 
being different than lower we could say that "M" = month and "m" =  
minute there would be no issues, but this is Impossible because the 
UPPER CASE web is Pointless, why well the simplest answer I can give is, 
The main reasons people build website s the first is to talk about your 
hot product and make money or talk about things that make you tick, The 
second (an perhaps more importantly to some) to be indexed by search 
engines and rank highly in their results. Most search engines use a 
process called Stemming[1]   or Porter 80  The Porter Stemming 
Algorithm[2] so this process can be done reliably first all html 
documents are converted to lower case  (this makes it easier to 
determine term vectors[3])  so any "semantic meaning" you may have 
marked up in there in  UPPER CASE  is  lost and means nothing.

Anyway finished with my rant  :-)     

This issue really  needs to be addressed some how though ?

Best wishes
