close #10469

use custom column names in pulses

Related Documentation of date format:
https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatter.html



In pulse notification I found out (works since yesterday until
tonight) that a timetamp formatted by a Pulse would output "Dec 31,
2020" for today's date (instead of "Dec 31, 2019").
This is because of the confusion between "YYYY" (the week based year,
this week is the 1st week of 2020) and "yyyy" formatting (the era
based year - thus the commonly expected year for a single day format).
