Depending on the location, the amount of time to travel from point A to point B varies the further the distance, the more time is passed. Taking the Dee-Dee Transport System passes time due to the player traveling to a different location, though off-screen.

Regardless of time of day, the player can sleep in bed until the next morning at 7:00. Going to bed can pass time to the next day. Entering the Sewage Plant, Ingall's Mine, Deepest Ruin, or Haunted Cave will consume a set amount of time upon entry, though time is completely frozen while inside. Time only stops when opening an interface (such as a menu, the inventory, or shop menus), speaking to an NPC, or entering any Hazardous Ruins (including those encountered only during missions) or the Haunted Cave. Time passes as long as the player idles in the overworld. The Dee-Dee Transport System runs from 7:00-1:30. If the player wishes to avoid passing out, it is advised that if one is working far from one's home, they should get to the nearest Dee-Dee Stop and/or ride a mount to get to bed on time. There are no penalties for passing out at 3:00. If 3:00 passes before the player goes to sleep, then the player will pass out and wake up in bed at 7:00 (or be teleported to their home if they do not have a bed placed there). Hours between 3:00 and 7:00 are inaccessible. The player awakens at 7:00 and is able to stay up until 3:00 in the morning. Game time is measured in the 24-hour clock, meaning that 1:00 pm is displayed as 13:00, 11:59 pm is 23:59, and midnight is 00:00. The game speed can be altered using the game speed slider in the settings. At the default game speed, a single uninterrupted in-game day from 7:00 to 3:00 is a minimum of 15 real-world minutes, provided that nothing pauses the game, including opening the inventory. Time in My Time at Portia is measured in hours and minutes that are relative to real-world time, with one minute in Portia equaling slightly less than one second in real time.
