* Support formatv of TimePoint with strftime-style formats.Sam McCall2017-10-241-25/+27
| | | | | | | | | | | | | | | | Summary: Support formatv of TimePoint with strftime-style formats. Extensions for millis/micros/nanos are added. Inital use case is HH:MM:SS.MMM timestamps in clangd logs. Reviewers: bkramer, ilya-biryukov Subscribers: labath, llvm-commits Differential Revision: https://reviews.llvm.org/D38992 llvm-svn: 316419
* [Support] Add FormatVariadic support for chrono typesPavel Labath2017-02-071-0/+31
| | | | | | | | | | | | | | | | 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 llvm-svn: 294326
* Reapply "Add Chrono.h - std::chrono support header"Pavel Labath2016-10-201-0/+79
| | | | | | | | | This is a resubmission of r284590. The mingw build should be fixed now. The problem was we were matching time_t with _localtime_64s, which was incorrect on _USE_32BIT_TIME_T systems. Instead I use localtime_s, which should always evaluate to the correct function. llvm-svn: 284720
* Revert "Add Chrono.h - std::chrono support header"Pavel Labath2016-10-191-79/+0
| | | | | | | | | This reverts commit r284590 as it fails on the mingw buildbot. I think I know the fix, but I cannot test it right now. Will reapply when I verify it works ok. This reverts r284590. llvm-svn: 284615
* Add Chrono.h - std::chrono support headerPavel Labath2016-10-191-0/+79
Summary: std::chrono mostly covers the functionality of llvm::sys::TimeValue and lldb_private::TimeValue. This header adds a bit of utility functions and typedefs, which make the usage of the library and porting code from TimeValues easier. Rationale: - TimePoint typedef - precision of system_clock is implementation defined - using a well-defined precision helps maintain consistency between platforms, makes it interact better with existing TimeValue classes, and avoids cases there a time point is implicitly convertible to a specific precision on some platforms but not on others. - system_clock::to_time_t only accepts time_points with the default system precision (even though time_t has only second precision on all platforms we support). To avoid the need for explicit casts, I have added a toTimeT() wrapper function. toTimePoint(time_t) was not strictly necessary, but I have added it for symmetry.
