I can not understand the command from the systemd?

Code:
journalctl --since "tomorrow"

By idea to show magazines from tomorrow. As it is illogical.
Tell me what is the essence of the team with the key tomorrow?

Weather::Com::DayForecast(3pm)				User Contributed Perl Documentation			    Weather::Com::DayForecast(3pm)

NAME
Weather::Com::DayForecast - class representing a forecast for one day SYNOPSIS
[...] my @locations = $weather_finder->find('Heidelberg'); my $forecast = $locations[0]->forecast(); my $tomorrow = $forecast->day(1); print "Forecast for tomorrow: "; print " - tomorrow it's the ", $tomorrow->date()->date(), " "; print " - sunrise will be at ", $tomorrow->sunrise()->time(), " "; print " - maximum temperature will be ", $tomorrow->high(), " "; DESCRIPTION
Via Weather::Com::DayForecast objects one can access the weather forecast for one specific day. This class will not be updated automatically with each call to one of its methods. You need to call a method of your Weather::Com::Forecast object to get updated objects. CONSTRUCTOR
You usually would not construct an object of this class yourself. This is implicitely done when you call the "day(number of day)" or the "all()" method of a Weather::Com::Forecast object. METHODS
date() Returns a Weather::Com::DateTime object containing the date the forecast is for. high() Returns the maximum temperature that will be reached at daytime. For day 0 (today), this will be 'N/A' when it's after noon... There is a bug in weather.com's date and time mathematics: If you are asking for a location's forecast day 0 and it's short after midnight, day 0 will be "yesterday" and you'll get both, yesterday's daytime forecast and night forecast! I have not investigated this issue further, yet. If anyone has, please inform me! low() Returns the minimum temperature that will be reached at night. sunrise() Returns a Weather::Com::DateTime object containing the time of sunrise. sunset() Returns a Weather::Com::DateTime object containing the time of sunset. day() Returns a Weather::Com::DayPart object with all data belonging to the daytime. For day 0 (today), this will be "undef" when it's after noon... There is a bug in weather.com's date and time mathematics: If you are asking for a location's forecast day 0 and it's short after midnight, day 0 will be "yesterday" and you'll get both, yesterday's daytime forecast and night forecast! I have not investigated this issue further, yet. If anyone has, please inform me! night() Returns a Weather::Com::DayPart object with all data belonging to the night. AUTHOR
