Field Detail

UTC

public static final TimeZone UTC

The UTC time zone. Not sure if TimeZone.getTimeZone(String) understands "UTC" in all environments, but it'll fall back to GMT in such cases, which is in practice equivalent to UTC.

MIDDAY

public static final TimeZone MIDDAY

Custom time zone used to interpret date values without a time component in a way that most likely falls within the same day regardless of in which time zone it is later interpreted. For example, the "2012-02-17" date would map to "2012-02-17T12:00:00Z" (instead of the default "2012-02-17T00:00:00Z"), which would still map to "2012-02-17" if interpreted in say Pacific time (while the default mapping would result in "2012-02-16" for UTC-8).
