When will the total international (outside mainland China) cases of COVID-19 exceed the total cases within mainland China?

Question

On December 31, 2019, the World Health Organization (WHO) was informed of an outbreak of “pneumonia of unknown cause” detected in Wuhan City, Hubei Province, China – the seventh-largest city in China with 11 million residents.

The Center for Systems Science and Engineering (CSSE) visualises and tracks the reported cases on a daily timescale.

The case data visualized is collected from various sources, including WHO, U.S. CDC, ECDC, China CDC (CCDC), NHC and DXY. DXY is a Chinese website that aggregates NHC and local CCDC situation reports in near real-time, providing more current regional case estimates than the national level reporting organizations are capable of, and is thus used for all the mainland China cases reported in our dashboard (confirmed, suspected, recovered, deaths).

Based on Johns Hopkins monitoring dashboard, as of March 3rd 2020 (14:03:04 UTC+1), 11,169 cases of coronavirus have been confirmed in locations outside of mainland China, with 80,151 cases confirmed within mainland China for a total of 91,320 confirmed cases worldwide.

When (UTC) will John Hopkins' CSSE first record the total cases within mainland China as less than half the total worldwide cases? I.e. when would John Hopkins' CSSE first record cases outside mainland China surpassing cases within mainland China?

If the John Hopkins tracker goes offline, then other trackers that may be considered:

This question retroactively resolves 1 day before the time when the CSSE tracker has cases outside mainland China surpassing cases inside mainland China.
