To show the date or time value in a specific format, use the Format function in combination with format codes.
Examples:
Show a date in the format "Monday, August 3":
=Format(Injection_AcquiredDate,"dddd, MMM d")
Add the GMT time offset information to a date, in the format "05/05/2015 3:50:00 AM GMT+2:00":
=Injection_AcquiredDate & " GMT" & Format(Injection_AcquiredDate,"zzz")
Show the date in ISO-8601 standard format, as in the OpenLab CDS application:
=Format(Injection_AcquiredDate,"yyyy-MM-dd HH:mm:sszzz")
This format is recommended in a compliant environment. It shows the date and time unambiguously for all time zones in the world.
