Edit Explaination:
The error is occurring because you are incorrectly parsing the date before passing it to DateTime.DateTimeParse.
DateTime.DateTimeParse requires 2 Strings
Try:

B4X:

    DateTime.DateFormat="dd MMM yyyy"
    Dim L As Long = DateTime.DateTimeParse("12 MAY 1920","02:00:00")
    Log(DateTime.Date(L))
    Log(DateTime.Time(L))

I need to get ticks from "12 MAY 1920"

B4X:

Dim L As Long = DateTime.DateTimeParse(DateTime.Date("12 MAY 1920"),"02:00:00")

and not separately date and time

You need to change the Date/Time output Format to display both:

B4X:

DateTime.DateFormat="dd MMM yyyy"
Dim L As Long = DateTime.DateTimeParse("12 MAY 1920","02:00:00")

DateTime.DateFormat="dd MMM yyyy HH:mm:ss"
Log(DateTime.Date(L))

Thank you, it works!
Tell me if it is possible not to specify the time "02:00:00". I don't need it.

Yes, just do:

B4X:

    DateTime.DateFormat="dd MMM yyyy"
    Dim L As Long = DateTime.DateParse("12 MAY 1920")
    Log(DateTime.Date(L))
