Hi @CLS720 ,
Which Time Zone does your SP Site set to? It is also set to Pacific Time zone?
Do you want to store the Date time values submitted from your PowerApps app to your SP list as they are from the Pacific Time zone?
Actually, the date time value stored within your SP list is based on the Time Zone of the end user who run this app.
Currently, when working date time values within PowerApps, the date time value would be converted into UTC format automatically.
In other words, the date time values submitted from your PowerApps app would be converted into UTC format time value firstly, then pass the formatted UTC time value to your SP list. Within your SP list, the formatted UTC time value would be converted to local time zone based on the time zone your SP Site set to.
If the Time Zone is different when the end users run this app, the time value submitted from this app would be converted into different UTC format time value, so the time value stored in your SP Site would be different.
If you want to maintain date/time entries submitted in other timezones as pacific time zone via PowerApps, I afraid that there is no direct way to achieve your needs in PowerApps currently.
As an alternative solution, when the end users submit date times from this shared app, you could consider ask them to convert the submitted time value into a Pacific Time zone (UTC-7) format firstly (using DateAdd function and TimeZoneOffset function), then submitted the formatted Pacific Time zone value into your SP Site.
I have made a test on my side, please take a try with the following workaround:
Within my Edit form, unlock the Start Time data card, set the Update property of the Start Time data card to following:
DateAdd( /* <-- Convert the UTC format value into Pacific Time zone value */
DateAdd( /* <-- Convert the end user's picked time value into the UTC format firstly */
DateValue1.SelectedDate + Time(Value(HourValue1.Selected.Value), Value(MinuteValue1.Selected.Value), 0),
TimeZoneOffset(),
Minutes
),
-7,
Hours
)
More details about how to convert a specific time value into a UTC format, please check the following article:
