I am using the Venus GPS and having issues with date and time. On closer inspection I get the following sentence:

$GPRMC,034115.316,A,3739.0937,S,14514.0468,E,000.0,048.2,08312,,,*7F

Initially I thought TinyGPS was breaking down the time incorrectly. Then I noticed the lack of leading "0"

  • 08312 - todays date 8th of March 2012 = 080312

It seems that about every 3rd entry is missing that leading 0. At this stage I am going to assume it is an invalid line, need to check the status. It might be performance issue and lost characters on the serial port, unlikely though.
