Bug? Return millisecond error

[cxbs]

hello everyone!
I found a strange error when converting timestamps,
I don't know what caused it
How to avoid this mistake
Thank you!
The above English is from translation software

DateTime.DateFormat="yyyy-MM-dd"
 DateTime.TimeFormat="HH:mm:ss.SSS"
    Dim t As Long=DateTime.DateTimeParse("1970-01-01","15:16:17.191")
    Log(t) '=83777190
    Log(DateTime.Time(t)) '=15:16:17.190

    Dim t As Long=DateTime.DateTimeParse("1970-01-01","15:16:17.192")
    Log(t) '=83777192
    Log(DateTime.Time(t)) '=15:16:17.192

Dear Mr. Erel
Thank you for your reply. I will verify it after each conversion.
