Basic Stamp 2 stopwatch

Hello!
I want to build a stopwatch with two decimals after seconds (up to
99:99). How to do? Start, Stop, Reset and display are ok, but with
the pocket watch B module I have only seconds! Someone has an idea? I
need help!
Many thanks in advance for your suggestions
Stefano

    Use an external RTC like the DS1302 (3-wire) or DS1307 (I2C). With
    either you can clear the registers when you press Start, then read them
    back when you press Stop. Simple.

    Many thanks for your aswer.
    I need more precision as a time clock (up tu 1/100 seconds).
    The DS1302 can give me this precision?
    Bye, Stefano

    Let me suggest that you read the DS1302 documentation -- it will answer all your
    questions about what it can and can't do.
