I wasn't sure where to put a thread like this so if I posted this topic in the wrong place I apologize in advance. When I tried to login this morning it said the server would be down until at least 1500 GMT/UTC. My question then is what time zone is this referring too? Also, how do I know whether they're referring to AM or PM?

The time zone is that stated in the fully-qualified time you posted. There's no such thing as AM/PM for a 24-hour based time.

GMT = Greenwich Mean Time (and obsolete and incorrect term, but still widely used out of habit). UTC (French) or UCT = Universal Co-ordinated Time. Replaced GMT many years ago.
You can figure out your own timezone. Here's mine: EST = Eastern Standard Time = UTC - 5 hours EDT = Eastern Daylight Time (daylight savings time) = UTC - 4 hours

If you are English, Greenwich Mean Time and indeed the place Greenwich (which still has the timeline running through it) very much still exsists no matter what the French or the rest of Europe wants to think with their daft UTC.

I was also under the impression that GMT and UTC are practically the same anyway.

They are NOT the same. Colloquially it is not a mistake to use GMT as a timezone. But technically they are different things.
GMT is an old (but still popular) term to refer to the mean solar time at the Royal Greenwich Observatory. This is a SOLAR time.
UTC is NOT a solar time, it's an atomic timescale time (measured by an atomic watch).
When subsecond astronomic precision is NOT needed but a predictable day length is desired, UTC is used. All timezones are defined as an offset from UTC.
For astronomical measures where subsecond precision is needed and the time MUST precisely indicate the actual rotation of the planet, the mean Greenwich time is used. But it is still no more called GMT because that had two meanings: it was used to refer to both a 0 at midnight and a 0 at noon timeframe. The modern correct term for it is UT1: Universal Time with corrections for polar motion.
A curiosity: UTC and UT1 (GMT) can differ by up to 0.9 seconds.

I thought it was the other way around. But at 0.9 seconds, for all intents and purposes they're the same thing on a human scale.

It couldn't be. GMT is an ancient term from long before atomic watches existed. It of course refers to a time that is derived from astronomical observations.
Originally by: F'nog But at 0.9 seconds, for all intents and purposes they're the same thing on a human scale.
The problem is not in the 0.9 seconds difference. It's in the fact that people think GMT has been renamed UTC and therefore they are the same thing. This is incorrect.
GMT has been abandoned because it referred to two different things: civil and astronomic time. It was supplanted with Universal Time. And the exact version of UT that replaced GMT is UT1, not UTC.
Not only GMT was replaced by UT1, but timezones stopped to be defined in terms of a solar time and switched to an atomic time. That's why today the timezones are defined from UTC and not from UT1.
Still, colloquially, it is accepted to use the term GMT to refer to the UTC timezone (still it's neither correct nor accepted to use GMT to refer to UTC time, but the distinction between universal time and the reference timezone is rarely an issue for common people: they are nearly always concerned with the timezone).

UTC is regularly adjusted to bring it into line with the rotation of the earth. This is why we have leap seconds added every few years. It's an exact time based on atomic clocks (which are based on the frequency of the caesium atom).
GMT is based on the rotation of the earth and therefore slightly irregular as the earth spins faster or slower and changes it's axis over time.
So UTC is regularly adjusted to make it as close as possible to GMT, so that the sun continues to rise and set at around the same time.......over many thousands of years, the sun would end up rising at lunch time if we didn't adjust.
For most practical purposes, GMT and UTC are the same and Eve Time can be based on either term used interchangeably. If you want to time your POS destruction operation to within less than a second, I suggest you use UTC. If you want everyone to turn up at midnight Eve Time, then GMT would be quite acceptable. If you're some sort of RL boffin who's trying to spot a distant star using the Hubble telescope, then the difference between UTC and GMT might become important.
No matter how much the proponents of UTC state that it's the be all and end all of time, it still gets adjusted to bring it back in line with the good old GMT on a regular basis.
For the purposes of playing the internet spaceship game called Eve, GMT/UTC are the same thing. Using Google and searching for "world time converter" or "UTC GMT Local Time" will give you a whole raft of options for working out what time you need to be online for your corporations next big mining op. You can even get pretty graphs that move and show you what time it is in different places. They can even show if it's day or night in a given location.

Everything you say is correct Baka. Except you should replace GMT with UT1.

UT1 is a more modern term, I prefer GMT. Being a former navy navigator, it just sits better with me. Also when I visited London, I didn't visit the UTC museum or the UT1 observatory.....it was the Royal Observatory in Greenwich. Some things just sound better.
Zulu is also a term that I would use. The military use letters to designate time zones - it's quick and easy to use one letter, rather than GMT+10. ______________________ Isn't it time you learned to fight back? Agony Unleashed Home of the PvP University.

Since we're on the subjective of time, I once worked across time zones where one observed Daylight Saving Time and the other did not. In the winter, the travel time was 2 hours to cover a 45 mile trip; whereas the reverse trip was completed in -15 minutes (I arrived 15 minutes before I left). When Daylight Saving Time was in effect, the trip took 1 hour, both directions.

I've had similar experiences here - in the far north of New South Wales you have to cross the border into Queensland to get to the airport to fly to Sydney (the capital of NSW). NSW has daylight savings, QLD doesn't. It makes for an interesting time to get to your plane - you leave home at 8am to catch a 7.45am flight (it's only 5mins to the airport), then you fly for 1 hour 15 minutes to arrive after 10am.

My thanks for everyone's help on this. I'm terrible at comparing time zones so all of this information was much appreciated! I thought the trivia on the subject was interesting as well On a side note, it was mentioned that the timer on this forum is the same as EVE time. Is there somewhere on the forums you can look for EVE time without having to post a message?

Look at the forum indexes for a recent post. This should fix you with the hour difference. Then just look at your local watch for the minutes. Unless ... you leave in one of those places where the local time is a fraction of an hour off the rest of the world.

Not on the forum, but open this link in a second tab or browser: World Time Clock and hit refresh. UTC is listed at the bottom of the city list.
There are others around that dynamically update, but you'll need to search for those, cos I'm feeling lazy. You can also get a number of applications that you could install, or if you're using Vista maybe a gadget. Linux has some utilities as well.
Another handy source is to use EveMon as it has the server time built in to the display.

It is absolutely acceptable to use GMT colloquially. Especially to refer to the timezone (that is instead of UTC), but also, if there's no possible ambiguity, to refer to UT1.
But if you are giving a definition as in "... is based on the rotation of the earth and therefore slightly irregular" or in "UTC is regularly adjusted to make it as close as possible to ...", then UT1 is the correct term.
In fact part of UTC specification is exactly that: it is adjusted periodically to stay within 0.9 seconds from UT1.
Note that colloquially GMT is often used in place of UTC (more often than it's used instead of UT1). Saying that "UTC is adjusted to stay close to GMT" is as correct as saying that "GMT is adjusted to stay close to UT1". In other words: you should not use GMT in that sentence because GMT does not have a unique meaning.
Originally by: Baka Lakadaka Zulu is also a term that I would use. The military use letters to designate time zones - it's quick and easy to use one letter, rather than GMT+10.
Zulu is how military/NATO would call UTC, yes. Or Kilo, for UTC+10.
