ID 95 Closed (Fixed) datetime2 1.0 DTMsaveaszulutime calculates the wrong UTC time

## Report

The DTMsaveaszulutime command appears to calculate the UTC time incorrectly. The example in the manual illustrates this: Original date: 2014-05-01 03:55:00-06:00. UTC+00:00: 2014-04-30 21:55:00Z. The original date is in the timezone UTC-6, so the corresponding UTC time should be 09:55:00, not 21:55 the previous day. If I save and print the current time using: \DTMsavenow{creationDate} \DTMtozulu{creationDate}{creationDateUTC} \DTMuse{creationDateUTC} I am given a UTC time of 18:20. My local time is 17:20 BST (= UTC+1), so the corresponding UTC time should be 16:20, not 18:20. (The minimal working example will only show the improper behaviour if the computer's timezone is not set to UTC.) As far as I can tell, this can be fixed by changing the line
\edef\@dtm@TZhour{\number#8}%
to
\edef\@dtm@TZhour{-\number#8}%
in the package's source code.
