[Remind-Fans] accepting dates/times in more English format

[hymie!]

Are you good with perl?  I'm almost positive there is at least
one perl module that will pretty much take any date/time format
you care to give it, and similarly output any format you choose.

Then you can hopefully regenerate your tables into remind's internal
format.

This example is pulled out of another script, and I haven't tested
it fully, but maybe it will help:

use DateTime;
use DateTime::Format::Strptime;
my $incoming = DateTime::Format::Strptime->new(
    pattern => "%b %d %Y %H:%M",
    time_zone => "UTC");
my $datestamp = 
   $incoming->parse_datetime("Jan 21 2019 19:59") ->
              set_time_zone("America/New_York");
print $datestamp->strftime("%Y/%m/%d@%H:%M\n");
