So, for example below is a timestamp generated by my Cassandra instance. What does the +0000 mean?
2015-06-26 17:02:04+0000
Thanks
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. What is T between date and time? The T is just a literal to separate the date from the time, and the Z means “zero hour offset” also known as “Zulu time” (UTC).
The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z).
From 822. GMT: +0000 (Greenwich Mean). From 822. HKT: +0800 (Hong Kong). IST: +0200 (Israel Standard) or +0530 (India Standard).
Universal Time Weather forecasts and observations are always made with respect to time. By convention, meteorologists use just one time zone: Universal Time, Coordinated (UTC). They also use the twenty four hour clock (where 0000 = midnight UTC).
It's the timezone offset. +0000 means UTC.
