Im doing a fetch to get a date from a database in java (the date should always be 2014-01-01T00:00:00). I'm getting the following time returned: 2014-01-01T00:00:00.588Z.
My questions is, what is the "588Z" at the end? and would this number be different the retrieve was done in a different timezone? i.e. would the number 588 be a different number in a different time zone.
Thanks for any help I may get.

The Z on the end means UTC (that is, an offset-from-UTC of zero hours-minutes-seconds). The Z is pronounced “Zulu”.
The literal "Z" is actually part of the ISO 8601 datetime standard for UTC times. When "Z" (Zulu) is tacked on the end of a time, it indicates that that time is UTC, so really the literal Z is part of the time.
The Z stands for the Zero timezone, as it is offset by 0 from the Coordinated Universal Time (UTC). Both characters are just static letters in the format, which is why they are not documented by the datetime.
That is a date “YYYY-MM-DD” with the four-digit Year, two-digit month and two-digit day, “T” for “time,” followed by a time formatted as “HH:MM:SS” with hours, minutes and seconds, all followed with a “Z” to denote that it is Zulu format.
The Z stands for the zero UTC offset.
If the time is in UTC, add a Z directly after the time without a space.
Z is the zone designator for the zero UTC offset.
"09:30 UTC" is therefore represented as "09:30Z" or "0930Z", while "14:45:15 UTC" would be "14:45:15Z" or "144515Z".
The portion immediately before the Z translates into fraction of second; here, 588.
From your question above, 00:00:00.588 means "about a half second past midnight", with the last three digits after the period, 588, translating: milliseconds.
... more details here on (ISO 8601 standard).

Z stands for UTC (that is GMT, but standard): http://en.wikipedia.org/wiki/Coordinated_Universal_Time
