-| startup.timeline.clock_ticks_per_second |[counter](https://mozilla.github.io/glean/book/user/metrics/counter.html) |The number of clock tick time units that occur in one second on this particular device. This value is expected to be used in conjunction with the `framework_start` metric.  |[1](https://github.com/mozilla-mobile/fenix/pull/9788#issuecomment-610648980)||2020-10-01 |
-| startup.timeline.framework_start |[timespan](https://mozilla.github.io/glean/book/user/metrics/timespan.html) |The duration the Android framework takes to start before letting us run code in `*Application.init`. This is calculated from `appInitTimestamp - processStartTimestamp`. `processStartTimestamp` is derived from the clock tick time unit, which is expected to be less granular than nanoseconds. Therefore, we convert and round our timestamps to clock ticks before computing the difference and convert back to nanoseconds to report. For debugging purposes, `clock_ticks_per_second`, which may vary between devices, is also reported as a metric.  |[1](https://github.com/mozilla-mobile/fenix/pull/9788#issuecomment-610648980)||2020-10-01 |
-| startup.timeline.framework_start_error |[boolean](https://mozilla.github.io/glean/book/user/metrics/boolean.html) |An error when attempting to record `framework_start` - the application init timestamp returned a negative value - which is likely indicative of a bug in the implementation.  |[1](https://github.com/mozilla-mobile/fenix/pull/9788#issuecomment-610648980)||2020-10-01 |
