[pkg-go] Bug#856314: HTTP API does not understand non-UTC date values

[Edward Lang]

Package: prometheus
Version: 1.5.2+ds-2
Severity: normal

When I call the Prometheus HTTP API using a localized date string, the API
cannot parse it to a valid timestamp. Changing the string to UTC / Zulu
makes the API work.

Examples:

Invalid URL:

http://localhost:9090/api/v1/query_range?query=node_load1{instance=
"localhost:9100",job="node"}&start=2017-02-27T21:19:19+08:00&end=2017-02-28T00:19:19+08:00&step=60m

Response:

{"status":"error","errorType":"bad_data","error":"cannot parse
\"2017-02-27T21:19:19 08:00\" to a valid timestamp"}

Valid URL:

http://localhost:9090/api/v1/query_range?query=node_load1{instance=
"localhost:9100",job="node"}&start=2017-02-27T13:20:02Z&end=2017-02-27T16:20:02Z&step=60m

Valid response:

{"status":"success","data":{"resultType":"matrix","result":[{"metric":{"__name__":"node_load1","instance":"localhost:9100","job":"node"},"values":[[1488205202,"0.1"],[1488208802,"0"],[1488212402,"0"]]}]}}
