Getting this warning, help me understand this

"C:\Users\XYZ\Anaconda3\lib\site-packages\qiskit\providers\models\backendconfiguration.py:337: UserWarning: dt and dtm now have units of seconds(s) rather than nanoseconds(ns). warnings.warn('dt and dtm now have units of seconds(s) rather ' "

Thanks

• Hi, please clarify what is your problem. Dec 30 '19 at 19:03
• Would it be possible to edit a minimal (not) working example of code into this, so that we have some context to go from? Thanks Jan 1 '20 at 10:27

This is just a warning to let you know that the API has changed for the backend configurations such as PulseBackendConfiguration. The dt (qubit drive channel timestep) and dtm (measurement drive channel timestep) parameters were previously specified in nanoseconds, but they are now specified in seconds. If you're not doing anything so advanced as to directly use these parameters, you can safely ignore the warning.
