Because datepicker is moved to Semantic Forms, date time picker (SFI_DateTimePicker.php) can no longer call SFIDatePicker
Topic on Extension talk:Semantic Forms Inputs
Normally this should not be a problem. The class is still available. Did you update SemanticForms?
Yes both SemanticForms and SemanticFormInputs are updated via git clone.
However command "grep -r SFIDatePicker ." under both SemanticForms and SemanticFormInputs directories return only calls to the class in SFI_DateTimePicker.php, no class definition.

[root@server1 extensions]# git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/SemanticFormsInputs.git
[root@server1 extensions]# grep -r SFIDatePicker .
./SemanticFormsInputs/includes/SFI_DateTimePicker.php: $this->mDatePicker = new SFIDatePicker( $this->mInputNumber . '_dp', $dateString, $this->mInputName, $this->mIsDisabled, $this->mOtherArgs );
You are right. The class was renamed SFDatePicker when it was moved to SF.
In fact the new name is SFDatePickerInput.
I just fixed it.
I thinks it is "SFDatePickerInput".
Also there is a php notice now:
PHP Notice: Undefined property: SFISettings::$datePickerDisableInputField
I'll look at it tomorrow.
I put in a fix that unbroke it for me. Could you give it a try?
