OMEdit export variables : time formatting precision inadequate

[Natopsi]

Description

When exporting data as CSV from OMEdit GUI, time column format have a format reduced to 7 or 8 significant digits single precision thus doesn't allowing proper exploitation of data with fine time steps.
The data columns have a proper double precision compatible formatting.

Steps to Reproduce

Example:
Run Modelica.Electrical.Analog.Examples.Rectifier with equidistant time grid unchecked and CSV as output format
Export any variable as CSV with Export Variables from GUI

Lines 188 and 189 of Rectifier_res.csv generated by OM Simulator starts with:
0.001492868956501593,
0.001492869025532345,

Lines 188 and 189 of the exported csv starts with (I included the first exported variable to show the different precision)
0.00149287,517.3252174227919
0.00149287,517.3252151192146

Expected Behavior

Time column of a CSV export from OMEdit should have a formatting compatible with double precision data.

Version and OS

• OpenModelica Version: 1.19.2 (64 bit)
• OS: Windows 10, 64 bit
• Modelica libraries 4.0.0

Additional Context

Looking at source code, in OMEdit/OMEditLIB/Plotting/PlotWindowContainer.cpp
Time is formatted with with QString::number(); while StringHandler::number() is used for the variables.
Maybe using StringHandler::number() can be sufficient.
