Logging Date Objects

Hey everyone!

I’m looking for a way to log Dates. I want to show the evolution of our labeled data over time over non-uniform time steps. To make it more clear, let’s say I want to display the amount of data on arbitrary days. If I ran my W&B run on those days, I could distinguish them by run:createdAt. The plots could display them as dates as one would expect and everything is fine. Now, this fails as soon as I want to have a starting date AND an end date. Therefore I’m looking to log date data.

The functionality should be there, as it is for createdAt, but I can’t figure out how to log my own. I couldn’t find a suitable object in the docs and neither POSIX timestamp nor iso format/datetime objects work out of the box.

Is there no way to do this, or did I overlook something?

As a workaround I could just use the POSIX timestamp as scale, but I guess we all agree that’s a little unwieldy.

Hi Thomas,

I looked into this and it looks like there is no good way to upload date data currently. I agree that this is definitely something we want to support, I’ll create a feature request for this and keep you updated on the progress of this feature.

For now, a POSIX timestamp is the only way to upload this data.
