Hello,
You can see the NCL code used via:
%> less $NCARG_ROOT/lib/ncarg/nclscripts/csm/diagnostics_cam.ncl
If you want you can extract an modify codes to fit your needs.
===
Maybe:
nDayWin = 30 ; Wheeler-Kiladis [WK] temporal window length (days)
nDaySkip = -10 ; time (days) between temporal windows [segments]
; negative means there will be overlapping
temporal segments

I guess I did not do the 'significance' for these Space-Time plots.
However, the "MJO CLIVAR" link ...see
