Subject cvs commit: ant/src/main/org/apache/tools/ant Diagnostics.java
Date Thu, 07 Apr 2005 17:07:34 GMT

  Modified:    src/main/org/apache/tools/ant Diagnostics.java
  Log:
  looking@why my junit reports are apparently an hour old. No fix, but -diagnostics now prints
some clock info, and examines diffs between temp dir and local clock and complains if they
are too different. (>10s, purely arbitrary)
