[Debian-med-packaging] Bug#1150961: bali-phy: FTBFS with fmt 12 due to removal of fmt::localtime

[Aron Xu]

Source: bali-phy
Version: 4.1+dfsg-1
Severity: important
Tags: ftbfs
Control: affects -1 src:fmtlib
X-Debbugs-Cc: fmtlib at packages.debian.org, aron at debian.org

bali-phy fails to build with fmt 12.1.0+ds1-1 during the fmtlib transition
rebuild on arm64:

  https://release.debian.org/transitions/html/auto-fmtlib.html

To reproduce, rebuild in sid with libfmt-dev from experimental.

fmt 12 removed the deprecated fmt::localtime API. Please replace these
calls with a supported local-time conversion:
