Zulu is GMT -1. Absolutely universal and is therefore called UTC
(Universal Time Coordinated). No confusion and no misunderstandings
possible.

No idea how you could change it permanently. Is it possible btw?
Never tried on my Pixel.

Definitely wrong.

During DST GMT is Zulu +1
GMT is Zulu during winter.

Exactly the reason why UTC was invented in 1972 and strictly speaking
GMT does not exist anymore:

Coordinated Universal Time or UTC is the primary time standard by which
the world regulates clocks and time. It is within about one second of
mean solar time (such as UT1) at 0° longitude (at the IERS Reference
Meridian as the currently used prime meridian) and is not adjusted for
daylight saving time. It is effectively a *successor to Greenwich Mean
Time* (GMT).

The coordination of time and frequency transmissions around the world
began on 1 January 1960. UTC was first officially adopted as CCIR
Recommendation 374, Standard-Frequency and Time-Signal Emissions, in
1963, but the official abbreviation of UTC and the official English name
of Coordinated Universal Time (along with the French equivalent) were
not adopted until 1967.[1]

The system has been adjusted several times, including a brief period
during which the time-coordination radio signals broadcast both UTC and
"Stepped Atomic Time (SAT)" before a new UTC was adopted in 1970 and
implemented in 1972.

For people who do not understand the concept:

Are you sure? What I just read indicates Zulu = UTC = GMT.

I usually change the filenames as soon as I dump the photos to the

GMT doesn't change in the summer. In the summer clocks in the UK change to
BST which is GMT+1.

Sorry, you've got it wrong. The UK operates on what used to be called
GMT during winter; in summer we operate on BST (British Summer Time).

GMT, when it was used, never varied by an hour. The old equation
was BST = GMT + 1.

Sorry, but that is completely wrong.

GMT, UTC and Zulu are equivalent and always the same. GMT does not move between
summer and winter.

In the UK (where I have always lived), we set our clocks to GMT in the winter,
and in March we move them forward an hour to GMT+1, which we call BST, for
British Standard Time. We move the clocks back to GMT in October.

When I used to do amateur radio, we were required to keep our logs in GMT all
year round. During the periods of BST, it was necessary to subtract an hour
from clock time when filling in the log.

Still, UTC ≠ GMT

https://en.wikipedia.org/wiki/Coordinated_Universal_Time

Coordinated Universal Time or UTC is the primary time standard by which
the world regulates clocks and time. It is within about one second of
mean solar time (such as UT1) at 0° longitude (at the IERS Reference
Meridian as the currently used prime meridian) and is not adjusted for
daylight saving time. It is effectively a successor to Greenwich Mean
Time (GMT).
....
The current version of UTC is defined by International Telecommunication
Union Recommendation (ITU-R TF.460-6), Standard-frequency and
time-signal emissions,[4] and is based on International Atomic Time
(TAI) with leap seconds added at irregular intervals to compensate for
the accumulated difference between TAI and time measured by Earth's
rotation.[5] Leap seconds are inserted as necessary to keep UTC within
0.9 seconds of the UT1 variant of universal time.[6] See the "Current
number of leap seconds" section for the number of leap seconds inserted
to date.

https://en.wikipedia.org/wiki/Greenwich_Mean_Time

Greenwich Mean Time (GMT) is the mean solar time at the Royal
Observatory in Greenwich, London, counted from midnight. At different
times in the past, it has been calculated in different ways, including
being calculated from noon;[1] as a consequence, it cannot be used to
specify a particular time unless a context is given. The term 'GMT' is
also used as one of the names for the time zone UTC+00:00 and,[2] in UK
law, is the basis for civil time in the United Kingdom.[3][a]

Sorry, my mistake. BST stands for British Summer Time.

It did stand for British Standard Time from 1968 to 1971, when they
experimented with remaining on BST = GMT+1 for the whole year instead of
reverting to GMT for the winter.

OK, so they are slightly differently defined, but in everyday practical
usage, they are the same.

Zulu is BST -1 at this time of year, but it is equal to GMT all the time
(hint GMT equals UTC which never changes)

Perhaps DST makes the difference. Here in The Colonies we'll be falling
back an hour in the near future.

I need to remember to look after the change and see if there's a difference.

All of this about the Brit/World time system is interesting, of course,

I never noticed before. Next time I take a shot with my Motorola I'll
see what it does. I'd do it now, but it needs a charge.

jhead looks at the exifinfo and changes stuff depending on what you tell
it to do. I tell it to change the filename to yyyymmdd-hhmmss.jpg. I
hate underlines and I don't need fractional seconds. I generally order
things by newest date/time,

alias dird='ls -altGF --color=yes |more'

and jhead works perfectly.

Not in all the colonies. Arizona hasn't had DST since 1968 (except
