Representation of pd.Timestamp is not ISO8601 compliant.

[kotval]

ISO 8601 specifies that the date and time portion of a timestamp is separated by a "T", but python's datetime.isoformat allows any character to separate them. To comply with ISO8601, line 650 should be changed to include a "T" in between the date and the time. Since this also complies with datetime.isoformat, there is no reason not to change this.

you can use strftime if you actually want to do this but why would we change this and break the world?

[TomAugspurger]

Agreed that we can't just change this.

[jreback]

and we use the isoformat from datetime already (which has a default sep argument of T)

[jreback]

@kotval the code you are referencing is simply a repr and not thr isoformat function - so this is no where implied even that this is ISO
