I landed a replacement Media.Duration2 histogram in https://codereview.chromium.org/2731513002
445361c39af42d3d14152f10a2ae9c786d5d0c68 @{#454783} which extends the max duration to 24 hours.

Requesting merge to 58. Safe UMA-only one-liner, and it'll be useful for other patches to get the new information 6 weeks earlier.

Your change meets the bar and is auto-approved for M58. Please go ahead and merge the CL to branch 3029 manually. Please contact milestone owner if you have questions.
