When looking at the METARs, the time is shown in 24 hr zulu, as it should (even though the colon is a bit redundant). However, when looking at the TAFs, unless you scroll down to the raw TAF data (assuming you have set it up under the "options"), the display shows the valid times in CUT and am and pm. I get that the CUT stands for coordinated universal time, but why am and pm? Why did iFly choose to change this from 24 hr time? It adds confusion in the mental calculations. When working with weather, we all work in zulu and 24 hr time. I looked for a way to change this display in the setups, but to no avail.
