Lawson's Landing tides chart

I just wanted to give everyone a heads up about their tide calendar.  Could it be wrong and it doesn't take into account DST?  For instance, 3/20's low of -0.20 is listed at 7:50AM, but the one on fishingreporters shows 6:46AM?!  Am I missing something (besides clams!  )?

I sent them an email about it so that they can correct it if it is a mistake.

it seems LL has the time wrong

Just got word from Lawson's and they'll be updating their chart.  There are still the printed ones floating around so please verify the time before heading out.

I have Tideapp on my android. check it out.
