'influx write' returns 'bad timestamp' with valid line protocol

[sanderson]

When using influx write to write data to InfluxDB 2.0, it returns a bad timestamp error for valid line protocol. If you add the same line protocol through the UI, it works.

Steps to reproduce:

1. Run the following commands:

   curl https://raw.githubusercontent.com/influxdata/influxdb2-sample-data/master/bird-migration-data/bird-migration.line --output ./tmp-data
   influx write -b test-bucket @./tmp-data

Expected behavior: I expect the data to write successfully.

Actual behavior: It returned a bad timestamp error for each line of line protocol.

Environment info:

• System info: Darwin 19.3.0 x86_64
• InfluxDB version: InfluxDB dev (git: b0d459fccf) build_date: 2020-03-17T20:02:22Z

Output example:

I'm also seeing what I believe to be related behavior in the UI. If I try to upload a file of line protocol (~800kb), the UI locks up and I have to hard refresh. However, if I copy and paste the contents of that file into the UI as just straight line protocol, it will write successfully.
