Precise only to microseconds. When stored, any additional precision is rounded down.
A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples:"2014-10-02T15:01:23Z"and"2014-10-02T15:01:23.045123456Z".
stringValue
string
A string value.
The string, represented as UTF-8, must not exceed 1 MiB - 89 bytes. Only the first 1,500 bytes of the UTF-8 representation are considered by queries.
The map keys represent field names. Field names matching the regular expression__.*__are reserved. Reserved field names are forbidden except in certain documented contexts. The map keys, represented as UTF-8, must not exceed 1,500 bytes and cannot be empty.
An object containing a list of"key": valuepairs. Example:{ "name": "wrench", "mass": "1.3kg", "count": "3" }.
