What are the available symbolics for temporal values?
That is, d is for days, m is for minutes, h is for hours, s is for seconds.
Are there any other symbolics specifically for months and years?

You can use ms for millisecond. There are no universally acceptable duration values for monts and years .
-W

I haven't found any mentioning of them in the Fusion manual.
I'm using 5.0.1

Thank you,
