if (value) {
    let splitTime = value.split(':')
    date = new Date()
    // If ...splitTime (spread operator) is used in below, compiler throws exeption - "Expected 1 or 4 arguments but got 0 or more" (I consider it as TS bug)
    date.setHours(splitTime[0], splitTime[1], splitTime[2]);
    // now I can use date string in my plugin
