Test is not so well of the ECC.
a) Maybe a great error in user
Place a ECSpinEdit on a form, change the Valueformat to evfTime and DateTimeFormat to hh:nn. If i compile, run and use the Buttons, nothing happens.
I think, the increments are not set correct for a timevalue, but where can i set the increments to a hour, a minute (or a second) ?!
b) I can set Buttons to none in the OI and Lazarus crashes full without a message

Edit:
ad a)
PageSize should be 0.04166666667 (=1/24 = hour)
Increment 0.000694444444 (=1/1440 = minute)
Min 0
Max 1
