timeHigh and timeLow are not UTC

[spidgrou]

Hi,
just installed some days ago.
It works pretty well, I see that the time of the tide is almost the same as table, 30 mins different, so you did a very good job if I think that this plugin works only on the depth.

I see that the time of the last low and high tide are not UTC, are in local time even if the date format says "Zulu".
I'm in NZ, Whangarei, so now I am on UTC+12 time zone, please see pics

in attach.

Setup:

• raspberry pi4 4Gb
• Openplotter 2
• Signal K 1.40.0

Thanks again.
Max
