Split time functionality into bevy_time (#4187) # Objective Reduce the catch-all grab-bag of functionality in bevy_core by minimally splitting off time functionality into bevy_time. Functionality like that provided by #3002 would increase the complexity of bevy_time, so this is a good candidate for pulling into its own unit. A step in addressing #2931 and splitting bevy_core into more specific locations. ## Solution Pull the time module of bevy_core into a new crate, bevy_time. # Migration guide - Time related types (e.g. `Time`, `Timer`, `Stopwatch`, `FixedTimestep`, etc.) should be imported from `bevy::time::*` rather than `bevy::core::*`. - If you were adding `CorePlugin` manually, you'll also want to add `TimePlugin` from `bevy::time`. - The `bevy::core::CorePlugin::Time` system label is replaced with `bevy::time::TimeSystem`.

Add default implementation of Serialize and Deserialize to Timer and Stopwatch (#6248) # Objective Fixes #6244 ## Solution Uses derive to implement `Serialize` and `Deserialize` for `Timer` and `Stopwatch` ### Things to consider - Should fields such as `finished` and `times_finished_this_tick` in `Timer` be serialized? - Does `Countdown` and `PrintOnCompletionTimer` need to be serialized and deserialized? ## Changelog Added `Serialize` and `Deserialize` implementations to `Timer` and `Stopwatch`, `Countdown`.

Update time by sending frame instant through a channel (#4744) # Objective - The time update is currently done in the wrong part of the schedule. For a single frame the current order of things is update input, update time (First stage), other stages, render stage (frame presentation). So when we update the time it includes the input processing of the current frame and the frame presentation of the previous frame. This is a problem when vsync is on. When input processing takes a longer amount of time for a frame, the vsync wait time gets shorter. So when these are not paired correctly we can potentially have a long input processing time added to the normal vsync wait time in the previous frame. This leads to inaccurate frame time reporting and more variance of the time than actually exists. For more details of why this is an issue see the linked issue below. - Helps with https://github.com/bevyengine/bevy/issues/4669 - Supercedes https://github.com/bevyengine/bevy/pull/4728 and https://github.com/bevyengine/bevy/pull/4735. This PR should be less controversial than those because it doesn't add to the API surface. ## Solution - The most accurate frame time would come from hardware. We currently don't have access to that for multiple reasons, so the next best thing we can do is measure the frame time as close to frame presentation as possible. This PR gets the Instant::now() for the time immediately after frame presentation in the render system and then sends that time to the app world through a channel. - implements suggestion from @aevyrie from here https://github.com/bevyengine/bevy/pull/4728#discussion_r872010606 ## Statistics ![image](https://user-images.githubusercontent.com/2180432/168410265-f249f66e-ea9d-45d1-b3d8-7207a7bc536c.png) --- ## Changelog - Make frame time reporting more accurate. ## Migration Guide `time.delta()` now reports zero for 2 frames on startup instead of 1 frame.
