Swift: convert NSDate to c# ticks

Question

i need to convert a NSDate to C# ticks.

DateTime.ticks converts date to ticks starting from January 1 0001.

How can i do that? Thanks in advance.

I borrowed this code somewhere, so I'm not an author. Here it goes:

   @implementation NSDate (Ticks)

    - (long long) ticks
    {
        double tickFactor = 10000000;
        long long tickValue = (long long)floor([self timeIntervalSince1970] * tickFactor) + 621355968000000000LL;
        return tickValue;
    }

    + (NSDate*) dateWithTicks:(long long)ticks
    {
        double tickFactor = 10000000;
        double seconds = (ticks - 621355968000000000LL) / tickFactor;
        return [NSDate dateWithTimeIntervalSince1970:seconds];
    }

    @end
