The date and time stamp showing under history is UTC.
All dates are stored as UTC in order for the audit trail to show correct order and so there is one database value for a date. Users will see the date and time showing hours ahead or behind their time zone.
See example of time zone conversions (Local Summer Time):
|Day Light Savings?||
|Non Local Summer Time||8:00 am||9:00 am||18:00 pm|
|Local Summer Time||8:00 am||10:00 am||19:00 pm|
