log show: --last 1m command ignored

Hi all

Wondering if anyone else has experienced this. Running MacOS Sierra 10.12.6 (16G29)

In Terminal, when I issue the log show --last 1m command, I get all log entries from the beginning of the month, as opposed to the last 1 minute.

I get the same output if I include --start and --end dates/times - all log entries starting oldest first.

It does not make a difference whether I include --predicate, --style, --info, --debug

Anyone else experienced this please? What am I doing wrong?

Thanks

James
