As far as I can see, none of the responses from @php.net has directly addressed this issue yet. Unfortunately, I don't currently have access to a testing environment on Windows, or I'd attempt to verify (or disprove) it myself. If noone else can do so, I may be able to do some testing on Windows NT some time in the next week. This may still be broken Windows behaviour -- it may even be due to attempting to calculate an intermediate local (negative) timestamp in timezones west of GMT -- but whatever the case, it probably needs some minor additional clarification on relevant pages. It may help to find out from the OP of #22620 what his timezone is, and whether gmmktime(0, 0, 0, 1, 2, 1970) correctly returns 86400. It may even be good public relations to request this anyway, just to show we are not completely ignoring his problem -- would anybody object if I did so? Cheers!
