python influxdbclient如何将精度设置为秒？

from influxdb import InfluxDBClient

# 创建InfluxDBClient对象
client = InfluxDBClient(host='localhost', port=8086)

# 切换到目标数据库
client.switch_database('your_database')

# 定义数据点
data = [
    {
        "measurement": "measurement_name",
        "tags": {
            "tag1": "value1",
            "tag2": "value2"
        },
        "time": "2022-01-01T00:00:00Z",  # 设置时间戳
        "fields": {
            "field1": 1,
            "field2": 2
        }
    }
]

# 写入数据点，并设置精度为秒
client.write_points(data, time_precision='s')
