Yearly recurring calendar items receive wrong dates when synced from Horde server to TB

[xj25vm]

Your environment

TbSync version: 4.8 Thunderbird version: 115.14.0 (actually I am using Betterbird - but hopefully it is the same as Thunderbird) Back-end: Horde 5.2.10 OS: Linux Slackware 64 bit

The calendar items are already in Horde at the server end. They are syncronising fine with an older Thunderbird copy - Thunderbird 60.9.1 with TBSync 1.7.0.2

I have sent a debug log via email

Expected behavior

Sync calendar items from the server to Thunderbird while preserving dates ...

Actual behavior

Yearly recurring calendar items receive a different date during sync from the server to TB - seemingly about 6 months into the future ...

Steps to reproduce

Configure TBSync in Exchange mode against Horde as a back-end and sync data set from the server to Thunderbird. Check the dates of yearly recurring calendar items
