Shwetha G S commented on OOZIE-675:
-----------------------------------

Yes, your understanding of the issue is right.

today(0,0) points to start of today(00:00 hours). This can't be done by date 
formatting. we use today(0,0) to specify start instance of a dataset(instead of 
coord:current)
                
> checkMultipleTimeInstances doesn't work for EL extensions

> To guard against specifying multiple instances in instance tag, 
> CoordSubmitXCommand.checkMultipleTimeInstances checks for ',' in instance 
> tag. This breaks for EL extensions. We have EL extension today(0,0) which 
> maps to start day of nominal time. today(0,0) resolves to a single instance 
> and presence of ',' doesn't imply that it resolves to multiple instances
> Can you please fix this
