Do not assume it does. Time abroad and any reset or exception rules require individual assessment on the actual history; a short absence is not an automatic fresh allowance.
Review the actual option before making travel commitments
Provide the full record and proposed next assignment. Have the applicable rules and process assessed rather than treating a departure and return as a guaranteed way to obtain additional work time. Assume nothing about the effect of a departure until the actual record has been reviewed, and take travel decisions in that order rather than the reverse.
The costly version of this mistake is a trip made specifically to produce a reset, with the return flight, the project start and sometimes a family move already booked around it; if the applicable rules do not treat the absence the way the plan assumed, all three commitments have to be unwound at once. Provide the full history and the proposed next assignment, and have the applicable rules and process assessed on those facts. While the assessment runs, useful preparation continues: document time abroad as it happens, keep evidence of where the person actually was, and hold the bookings that depend on the outcome.
Recording an absence properly costs nothing at the time and is impossible to reconstruct afterwards.
