128000000000000000

Microsoft NT counts time as the number of 100-nanosecond ticks since 1601-01-01T00:00:00Z (1 January 1601 00:00:00 Universal Time.) I just happened to notice that the NT clock struck 128000000000000000 a few days ago, specifically at 2006-08-14T03:33:20+00:00 (14 August 2006 03:33:20 Universal Time.)

You can easily compute that using the following Chronos code:

ChronosFunction 
    daysAndSecondsSinceStartOfDayFromSeconds: 128000000000000000 // 10000000
    into: [:days :seconds | 
           Timepoint 
             daysSinceEpoch: days + (YearMonthDay year: 1601 day: 1) daysSinceEpoch 
             seconds: seconds 
             timeZone: #UT]

If you'd prefer to have the result computed relative to your local time zone, use the following variation:

ChronosFunction 
    daysAndSecondsSinceStartOfDayFromSeconds: 128000000000000000 // 10000000
    into: [:days :seconds | 
           Timepoint 
             utDaysSinceEpoch: days + (YearMonthDay year: 1601 day: 1) daysSinceEpoch 
             seconds: seconds]
