FlexNet Operations (FNO) treats a license day as ending at 11:59:59 PM Pacific Time (PDT).
So, according to the license server, a “day” resets at that exact time in the PDT time zone.
On the client side (your machine), when you borrow a license “for a day,” the actual expiration is based on your computer’s local time zone, not PDT.
This means:
The license will stay checked out until the end of your current day (your local 11:59:59 PM).
The duration is calculated as the number of seconds from now until 11:59:59 PM in your time zone.
Example
If you are in Central Time (CT) and borrow a license at 3:00 PM CT:
Your machine calculates: time remaining in the day = from 3:00 PM to 11:59:59 PM CT.
So the license will stay checked out until 11:59:59 PM CT, not PDT.
FNO internally uses PDT for feature expiration.
But the client (FlexNet license borrower) uses local time when calculating the borrow end time.
Bottom line
The license server defines expiration in PDT, but when you borrow a license “for a day,” your PC uses your own time zone, so the license returns at the end of your local day.
