Summary0004103: rpm tables get expanded to and written in real time, not user time
DescriptionWhen setting a rotating wall velocity and rpm with Table Function1, using a tool that expands the rpm function and writes it back (like setFields, but also createNonConformalCouples shows the same behaviour for our simulations), the written result is in real time, not user time.
Steps To ReproduceRun the following in tutorials/XiFluid/kivaTest:

#!/bin/sh
cd ${0%/*} || exit 1 # Run from this directory

# Source tutorial run functions
. $WM_PROJECT_DIR/bin/tools/RunFunctions

# Get application name
application=$(getApplication)

runApplication kivaToFoam -file otape17

cp $FOAM_ETC/caseDicts/annotated/setFieldsDict system/
cp -R -- -180 0

foamDictionary -entry defaultFieldValues -set '(volVectorFieldValue U (0 0 0))' system/setFieldsDict
foamDictionary -entry regions -set '()' system/setFieldsDict

foamDictionary -entry boundaryField/liner/type -set rotatingWallVelocity 0/U
foamDictionary -entry boundaryField/liner/axis -set '(0 0 1)' 0/U
foamDictionary -entry boundaryField/liner/origin -set '(0 0 0)' 0/U
foamDictionary -entry boundaryField/liner/rpm -set 'table ((0 0) (10 100))' 0/U

runApplication setFields -time 0

#------------------------------------------------------------------------------
Additional InformationThe liner entry in 0/U reads as

    liner
    {
        type rotatingWallVelocity;
        origin (0 0 0);
        axis (0 0 1);
        rpm
        {
            type table;
            values
2
(
(0 0)
(0.00111111 100)
)
;
        }
        value uniform (0 0 -0);
    }


where I would expect that the expanded table should read as:

2
(
(0 0)
(10 100)
)
;
TagsNo tags attached.

To make things worse, if one decomposes the case, the entry for the rpm gets transformed again to real time, reading:

    liner
    {
        type rotatingWallVelocity;
        origin (0 0 0);
        axis (0 0 1);
        rpm
        {
            type table;
            values
2
(
(0 0)
(1.234566667e-07 100)
)
;
        }
        value uniform (0 0 0);
    }
