If it is 9 AM pacific time, it would be 11 AM central time.
When it's 3 PM CEST (UTC+2), the time in California is 6 AM PDT (UTC-7).
At 10 AM PDT, it's 10 AM MST in most of Arizona. Both PDT and MST are 7 hours behind UTC.
It is 1 hour earlier in PDT then it is in MST.
Two hours separate Pacific time from Central time, but when Pacific time is observing Daylight Savings, it means that that time zone is running one hour ahead than it would be under Pacific Standard time (PST).This means that CST is now 1 hour ahead of PDT, so the answer would be 12 noon. I believe the only time you would observe these two time zones operating under different Daylight savings modes would be when Pacific time has gone to Daylight savings (at 2am or whenever it happens), but Central time hasn't begun observing Daylight Savings yet.Daylight savings time is observed at the same time throughout the US, so the difference in time zones (PDT and CST) is still 2 hours, so it would be 1 pm CST.The North American Central Standard Time Zone is in a total of ten countries. Of the ten, the United States is the only one that almost never has an area that is in CST while the west coast is in PDT (except for 2 hrs. per year early on the 1st Sun. of Nov.).Central Standard Time (UTC - 6 hrs.) is 1 hr. ahead of Pacific Daylight Saving Time (UTC - 7 hrs.). So 1100 AM PDT = 1200 noon CST.Also...1100 AM PDT = 200 AM China Standard Time (CST)1100 AM PDT = 330 AM Central Standard Time in Australia (CST)Example: In July, when it's Monday at 11 AM PDT in California, it's Monday at 12 noon CST in Saskatchewan, Tuesday at 2 AM CST in China and Tuesday at 3:30 AM CST in South Australia.The comment in the first answer is now true regarding Cuba Standard Time. Since Cuba changed their Daylight Saving Time schedule in 2012, there is only four hours per year (05:00-09:00 UTC on the 1st Sun. of Nov.) when Pacific Daylight Saving Time and Cuba Standard Time are simultaneously in use.
7:30 pm PDT = 3:30 am BST
1800 hrs PDT = 1800 hrs MST.
