Yamamotoと申します。
現在Almaddilo460でC言語による開発を行っております。
時刻を色々と使用しているのですが、スクリプトでプログラムを起動時に自動実行させた
時と、ログインして手動で実行させたときで使用される時刻がJSTとUTCで変わっているよ
うで何故かご存知の方教えていただけませんでしょうか。
状況
１．date -s "050915002013.00" で13/5/9 15:00:00に設定
２．hwclock --systohc --utc でRTCにUTCで現在時刻を設定
hwclock の確認で-9時間表示を確認
３．Armadillo460の電源Off->Onで再起動
プログラム表示(gettimeofdayで取得、localtime値を表示)でUTCの日時が表示される。
４．ログインして、同じプログラムを手動実行するとJSTの日時が表示される。
