Hi all,
I am interested in the feature request #1397 [1], which requests that phpMyAdmin support fractional seconds in time, datetime and timestamp data types.
After bit of research I found that these data types support trailing fractional seconds up to microseconds (6 digits). For example, the syntax for datetime including fractional seconds would be '2013-04-23 11:21:07.145236'. This syntax is supported from version 5.0 [2], however the fractional seconds were discarded when storing. From version 5.6.4 onwards these fractional seconds are stored and hence this feature request is important.
I have looked into the code to implement this feature request and the major problem faced is the incompatibility of JavaScript timepicker used [4], which only supports up to milliseconds (3 digits). I have been improving this JS file to support microseconds, however it is a somewhat big change.
I'd like to know whether I should simply alter the external JS file in phpMyAdmin code or I should send a pull request to the timepicker project, so it will be a part of the timepicker project as well. However, with the second option it might take some time till they (hopefully) accept the patch and do a release containing it.
