Absolute Timestamps not correct

[moberhofer]

When using the absolute-timestamp option, the resulting timestamps are wrong. Only every second the timestamps changes.
This is due to the fact, that the multiplication with the np.timedelta64 with a floating point number does not seem to work.

pyDmdReader/pyDmdReader/_dmd_reader.py

Line 463 in 7af7952

timestamps = start_time_np + np.timedelta64(1, "s") * timestamps

Any update on this? Just realized the same problem.

Sorry we will look at this as soon as possible.

Maybe this workaround-example is useful to someone:

import pyDmdReader

# load file:
dmd = pyDmdReader.DmdReader('filename.dmd')

# read a channel. The index will be in seconds:
data = dmd.read_dataframe('temperature')

# convert the index to datetime. We use the start-time in UTC, this might be not correct but for my application it worked:
data.index = pd.to_datetime(data.index, unit='s',  origin=dmd.measurement_start_time_utc.tz_localize(None))
