Not all valid TimeSeries objects can be serialized

[vhirtham]

I am currently lacking the time to create a minimal reproducible example, but it seems like absolute times can not be serialized (correctly) with the current schema definition. You can see the problem in the file CSM_Multi_Pass_example_old in my scratch directory on the jupyter server. Just go to the cell that defines the function get_bead_data and change the lines

        curr_dat = w["UI"].U_HKS1
        curr = TimeSeries(Q_(curr_dat.data, "A"), Time(curr_dat.time).as_timedelta())

        volt_dat = w["UI"].I_HKS1
        volt = TimeSeries(Q_(volt_dat.data, "V"), Time(volt_dat.time).as_timedelta())

to

        curr_dat = w["UI"].U_HKS1
        curr = TimeSeries(Q_(curr_dat.data, "A"), curr_dat.time)

        volt_dat = w["UI"].I_HKS1
        volt = TimeSeries(Q_(volt_dat.data, "V"), volt_dat.time)

and run everything again from this cell on.

You will get a validation error during the serialization.

I guess it is the same error as this snippet:

import pandas as pd

from weldx import Q_, Time, TimeSeries, WeldxFile

data = Q_([1, 2, 3, 4], "m")
t = pd.date_range(start="2020-01-01", freq="1D", periods=4)
ts = TimeSeries(data, t)

WeldxFile(tree={"ts": ts}, mode="rw")
