Today I want to know how many different of PST and ICT. Sadly, I don’t know much about PST so I googled for  and found Time & Time Zone Conversion at TimeZoneConverter.com. For this service, you could use current date/time or specify by your own manually. Anyway, I got a bad time to find PST since there are America, US, and Pacific. I stucked at Ameica for long time until I found Pacific and then US. Eventually, I found US/Pacific which could be the best fit for me. Finding ICT was so easy because I know exactly it is Asia/Bangkok for sure.
