I think the question has already been answered, but to reduce confusion, perhaps include the time zone %Z to see what is happening...
Code:
$ date --date "1979-10-26" '+%Y%m%d%H %Z'
1979102600 GMTDT
$ date --date "1979-10-26 +54 hours" '+%Y%m%d%H %Z'
1979102805 GMTST
$ date --utc --date "1979-10-26 +54 hours" '+%Y%m%d%H %Z'
1979102806 UTC

If you are still "befuddled", then that is to be expected. The first page of info date provides a quote...

First, a quote:
Our units of temporal measurement, from seconds on up to months,
are so complicated, asymmetrical and disjunctive so as to make
coherent mental reckoning in time all but impossible. Indeed, had
some tyrannical god contrived to enslave our minds to time, to
make it all but impossible for us to escape subjection to sodden
routines and unpleasant surprises, he could hardly have done
better than handing down our present system. It is like a set of
trapezoidal building blocks, with no vertical or horizontal
surfaces, like a language in which the simplest thought demands
ornate constructions, useless particles and lengthy
circumlocutions. Unlike the more successful patterns of language
and science, which enable us to face experience boldly or at least
level-headedly, our system of temporal calculation silently and
persistently encourages our terror of time.
... It is as though architects had to measure length in feet,
width in meters and height in ells; as though basic instruction
manuals demanded a knowledge of five different languages. It is
no wonder then that we often look into our own immediate past or
future, last Tuesday or a week from Sunday, with feelings of
helpless confusion. ...

sttime
sttime(3) ShapeTools Toolkit Library sttime(3)NAME
stMktime, stWriteTime - date and time handling
SYNOPSIS
#include <config.h>
#include <sttk.h.h>
time_tstMktime (char *string);
char*stWriteTime (time_t date);
DESCRIPTION
stMktime scans the given string and tries to read a date and time from it. It understands various formats of date strings. The following is
a list of all valid formats, optional parts in brackets.
[Tue] Jan 5[,] [19]93
This includes the standard asctime(3) format.
Jan 5 With no year given, the year defaults to the current year.
[19]93/01/05 This notation requires month and day represented by exactly two digits.
5.1.[19]93 This is the usual German notation.
5.1. German notation referencing the current year.
A certain time, given together with the date must always have the following form.
hours:minutes[:seconds]
Each of the fields must be an integer value within the proper range (hours: 0-23, minutes and seconds: 0-59). Values below
10 may be written as one digit numbers.
The time value may be placed anywhere in the date string: at the beginning, at the end, or somewhere in the middle. Any amount of white-
space may be given between a field of the time value and the separating colon. The time is always considered to be local time.
stWriteTime generates a time string similar to asctime(3) from its date argument.
SEE ALSO asctime(3)BUGS
Time Zone Names within the time string (like `MET') are not handled properly. In most cases they will cause a failure.
