  Note that this value denotes the median service time
for cache hits. It does not say that there are not any hits.
As to why it is 0 , perhaps currently your squid is lightly loaded.

  That depends on your users Internet access profile (too).
  Suppose they are all accessing objects with short lifetimes.
  Theoretically that behavior could even be worse.

  You may have a light load , or you didn't wait long enough.
  It can take up to a week to fill the cache.
 
  What is your average http reqs/sec ?
