Time Zones
Examples for specifying the time zone:
Single Zone¶
Most graphs will only show a single time zone. By default the zone is US/Pacific. To set to
another zone such as UTC use the tz query parameter:
/api/v1/graph?
e=2012-01-01T00:00
&q=
name,sps,:eq
&tz=UTC
Multi Zone¶
The tz parameter can be specified multiple times in which case one X-axis will be shown per
zone. Start and end times will be based on the first time zone listed.
/api/v1/graph?
e=2012-01-01T00:00
&q=
name,sps,:eq
&s=e-2d
&tz=US/Eastern
&tz=US/Pacific
&tz=UTC
Daylight Savings Time¶
If using a time zone that changes for daylight savings time, then you will see duplicate or missing hours on the time axis labels during the transition period. For example, a duplicate hour:
/api/v1/graph?
e=2015-11-01T08:00
&q=
name,sps,:eq
&s=e-12h
&tz=US/Pacific
&tz=UTC
A missing hour:
/api/v1/graph?
e=2015-03-08T08:00
&q=
name,sps,:eq
&s=e-12h
&tz=US/Pacific
&tz=UTC
If looking at a longer time frame, then it can also throw off the alignment so ticks will not be on significant time boundaries, e.g.:
/api/v1/graph?
e=2015-11-05T08:00
&q=
name,sps,:eq
&s=e-1w
&tz=US/Pacific
&tz=UTC
