# Fix: Alpine needs ca-certificates to verify SSL certificates.
# tzdata + TZ: the database connection sets TimeZone=Asia/Kolkata, so
# CURRENT_TIMESTAMP defaults write IST wall-clock into the timestamp columns.
# With the container defaulting to UTC, every time.Now() the app wrote was 5h30m
# behind those defaults, and "today so far" date ranges ended 5h30m in the past —
# which silently dropped anything created after noon IST from every report.
RUN apk add --no-cache ca-certificates tzdata
ENV TZ=Asia/Kolkata
