tfactl analyze date format invalid value

I am trying to use tfa to analyze OSW logs for a specific period using -from -to clause.

I cannot find a date format that works e.g.

tfactl> analyze -from "2017-02-21 06:10:00" -to "2017-02-21 08:10:00"

ERROR: Invalid value for -for/-from. Supported format MMM/DD/YYYY HH24:MI:SS

tfactl> analyze -from "Feb/02/2017 06:10:00" -to "Feb/02/2017 08:10:00"

ERROR: Invalid value for -for/-from. Supported format MMM/DD/YYYY HH24:MI:SS

tfactl> help analyze
