Looking at Geckoview page_load_times timing distributions, some of the bins are only one nanoseconds wide.
This query: https://sql.telemetry.mozilla.org/queries/65670/
The binning:
7,692,387 2,502 0.01 0.17
8,388,607 5 0.00 0.17
8,388,608 1,937 0.00 0.17
9,975,792 1,518 0.00 0.18
No investigation has yet been performed. However -- some hypotheses:
This may be due to slightly different calculations between glean-core and glean-ac.
We may be seeing it coming from different Android SDK versions.
We should confirm we never see it coming from the same client.

The only cases where the "1 nanosecond less" buckets appears is from clients running Android SDK 22.
