Vancouver is 8 hours behind so it would be 10am. Both the UK and Canada have daylight saving times which change at roughly the same time but it may mean there are a few days per year in spring and autumn where the time difference would be different.
Melbourne is 17 hours ahead of Vancouver at the moment, so if it's 11am in Melbourne it's 6pm, -1 day in Vancouver.
If you are asking about the time differencebetween Dhaka, Bangladesh and Vancouver, Canada, Dhaka is located at GMT +6.00 hours and Vancouver is located at GMT -8.00 hours, where GMT is 0.00 hours. Therefore, when it is 4am Monday in Vancouver, it is 6pm Monday in Dhaka. If you are asking about the flying time from Dhaka to Vancouver, that would be approximately 14.5 non-stop hours. However, there are no non-stop flights operating between the two cities, so flying between the two would involve connecting flights. That would extend travel times considerably.
At either 12am or between the update time for the PS between 5-6pm
That would be 6pm.
6pm i think.
6pm 6pm
That depends on to which shopping mall you are referring. There is a shopping mall in downtown Vancouver called Vancouver Centre Mall, but it is a much smaller offshoot of Pacific Centre Mall. As of February 2016, Pacific Centre hours are Monday, Tuesday, and Saturday: 10am - 7pm; Wednesday, Thursday, and Friday: 10am - 9pm; Sunday: 11am - 6pm.
1800hrs
11pm
5 am
11am in EST (for example New York) would be 6pm in Ukraine.
It depends what part of Australia. In Canberra it would be 1000 (10am)
