in thread Display Specific Time on Any PC.

I'm having trouble following your spec. You have two ideas here:

  • A timestamp in epoch
  • A mapping to the local time
Some kind of interrogation has to occur in order to reveal what any given machine believes the answer to any question is. It seems like it should be as simple as having your server parrot a timestamp from your resource in Hawaii to the PC in Rome, and then you could have Rome convert that in JavaScript for display. Alternatively, you could interrogate the PC in Rome for a time zone, and format on the server. I'm not tracking where the issue is for you in implementing this.

    Only 1 idea. Show exact time at resource on a PC that is in a different time zone from the resource.

    "Well done is better than well said." - Benjamin Franklin

      #!/usr/bin/perl -w use strict; use DateTime; my $dt = DateTime->from_epoch( epoch => time() )->set_time_zone('Ameri +ca/Los_Angeles'); print $dt->hms(':');
      prints the current time in Los Angeles.
      #!/usr/bin/perl -w use strict; use DateTime; my $dt = DateTime->from_epoch( epoch => 1395697655 )->set_time_zone('E +urope/Rome'); print $dt->hms(':');
      prints what time it was in Rome when I wrote this code. You need two pieces of data:
      • Time zone for output
      • Time stamp to output
      and then you can output whatever time any computer thought it was, translated into local time. If this is not what you need, then I'm misunderstanding your spec. Please give specific data for what you expect to see.
