Summary: The formatter has three knobs: - the user can choose which time unit to use for formatting (default: whatever is the unit of the input) - he can choose whether the unit gets displayed (default: yes) - he can affect the way the number itself is formatted via standard number formatting options (default:default) Reviewers: zturner, inglorion Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D29481 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@294326 91177308-0d34-0410-b5e6-96231b3b80d8
