* timestamp: use rfc3339-formatted timestamps in output Replace localized timestamps with machine-readable IETF RFC 3339 format timestamps. This is an attempt to make the output timestamps easily machine-readable. ISO8601 specifies standards for time interchange formats. IETF RFC 3339: https://tools.ietf.org/html/rfc3339 defines a subset of these for use in the internet. The general form for these timestamps is: YYYY-MM-DDTHH:mm:SS[+-]hhmm This replaces the localized time formats that are currently being used in the benchmark output to prioritize interchangeability and machine-readability. This might break existing programs that rely on the particular date-time format. This might also may make times less human readable. RFC3339 was intended to balance human readability and simplicity for machine readability, but it is primarily intended as an internal representation. * timers: remove utc string formatting We only ever need local time printing. Remove the UTC printing and cosnolidate the logic slightly. * timers: manually create rfc3339 string The C++ standard library does not output the time offset in RFC3339 format, it is missing the : between hours and minutes. VS does not appear to support timezone information by default. To avoid adding too much complexity to benchmark around timezone handling e.g. a full date library like https://github.com/HowardHinnant/date, we fall back to outputting GMT time with a -00:00 offset for those cases. * timers: use reentrant form for localtime_r & tmtime_r For non-windows, use the reentrant form for the time conversion functions. * timers: cleanup Use strtol instead of brittle moving characters around. * timers: only call strftime twice. Also size buffers to known maximum necessary size and name constants more appropriately. * timers: fix unused variable warning |
