Thanks for the feedback, @Krinkle! @Mooeypoo, I have uploaded a new patch to address this: https://gerrit.wikimedia.org/r/c/mediawiki/core/+/598136

I have a question about this ticket: should the clock icon appear when there are multiple changes on the same day in a temporarily watched page? I have been testing this patch and the clock icon does not appear on temporarily watched pages with more than one edit in a day.

Question about the number that goes in the message: is it the total number of days a user will be watching the page (e.g. if a user selects 3 months, 90 will be the number always displayed), or the number of days a page has been watched (e.g. if a user temporarily watched a page for 3 months 2 days ago, the number will be 2). Maybe the phrasing of the sentence can be changed for better clarity?

@Aklapper: I have just connected my MediaWiki user to Phabricator. Let me know if I need to do something else!

I can now see the Code-Review+2 button. Thank you very much!
