Need help with Photos RAW+JPG (Canon) importation, as well as fixing time zones

[Dekema2]

When importing RAW+JPG pictures from my Canon 60D to Apple Photos, some are combined, most are separated. In addition, I took pictures in 6 different time zones (Guam, Japan and Pacific to name a few) and neglected to correct the camera time. How can I fix all of this? I tried using HoudahGeo to shift the times around, hoping that this might make a difference, to no avail.

In addition, when I look at iPhone pictures taken in some of these locations, they're not even close to when I remember taking them. So it feels like I'm juggling 3 different image times: the camera time, my iPhone time of similar pictures, as well as the local time here on the East Coast relative to the other time zones.

Curious what HoudahGEO did wrong? I thought that product was made to fix a problem like this?

I don't have suggestions for the RAW/JPG question. However, for the time zone adjustment you can do that directly in Photos:

Select all photos that require a particular adjustment (Control + Click or Shift + Click).
Image menu > Adjust Date & Time
