[Message part 1 (text/plain, inline)]

Dear Sir,
I have stumbled across this anomaly whilst processing a series of dates. 
I have not found any other legal date combination that generates this 
error. Perl time facilities seem to be affected by this too.

mjh <at> carnaby:~> date --date="2022/03/27 00:00:00"
Sun 27 Mar 00:00:00 GMT 2022

mjh <at> carnaby:~> date --date="2022/03/27 01:00:00"
date: invalid date ‘2022/03/27 01:00:00’

mjh <at> carnaby:~> date --date="2022/03/27 02:00:00"
Sun 27 Mar 02:00:00 BST 2022

The version of date is:
mjh <at> carnaby:~> date --version
date (GNU coreutils) 8.29
