APPLICATION COMPATIBLE LEAP SECOND SUPPORT

Exposing a leap second to a plurality of applications includes identifying a system setting enabling leap second support and that a positive leap second should be added to the end of a chosen date. Based on the system setting enabling leap second support and based on the occurrence of the positive leap second, a first conversion component is exposed to a first application. The first conversion component presents, over a period of two seconds of actual time, a last second of the chosen date as if it is one second of system time. Based on the system setting enabling leap second support, based on the occurrence of the positive leap second, and based on a second application opting in to leap seconds, a second conversion component is exposed to the second application. The second conversion component presents an extra 61st second of system time at the end of a last minute of the chosen date.
