CST (Central Standard Time) is 2 hours ahead of PST (Pacific Standard Time).
To convert CST to PST, subtract 2 hours:
CST → PST
10:00 AM CST = 8:00 AM PST
12:00 PM CST = 10:00 AM PST
5:00 PM CST = 3:00 PM PST
Keep in mind that during daylight saving time (DST), the offset may change to 1 hour for some regions.
