The code to trim trailing zeros from z (or zz, but not zzz) format correctly checked for whether the text ended with the locale's zero, but incorrectly chop(1)ed to remove the zero, neglecting the possibility that the zero is longer. Noticed while checking where else we used QLocale::zeroDigit() possibly naively. Add Fulah-Adlam tests for milliseconds, which confirmed the problem does actually appear. Fix dropping of trailing zeros from millis. Pick-to: 6.10 6.8 6.5 Change-Id: Id080f082b2890a102809ba8d0f687d55ac082357 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
