     1  ### `duration_precision()` {#fn-duration-precision}
     2  
     3  函数原型：`fn duration_precision(key, old_precision: str, new_precision: str)`
     4  
     5  函数说明：进行 duration 精度的转换，通过参数指定当前精度和目标精度。支持在 s, ms, us, ns 间转换。

     8  # in << {"ts":12345}
     9  json(_, ts)
    10  cast(ts, "int")
    11  duration_precision(ts, "ms", "ns")
    12  
    13  # Extracted data(drop: false, cost: 33.279µs):
    14  # {
    15  #   "message": "{\"ts\":12345}",
    16  #   "ts": 12345000000
