Description

ClockType controls whether times are displayed in 12-hour format (8:30 AM) or 24-hour format (08:30). In Europe, 24_hour is the common standard, while in the US 12_hour is mostly used. The Notes client and Domino take the value from the user preferences or the system locale; ClockType lets you override it explicitly.

Example configuration

ClockType=24_hour

Notes & pitfalls

  • Affects all display locations where Domino/Notes formats times (mail, calendar, console marks, view columns without explicit formatting).
  • For server-side logs, the OS time format often outweighs ClockType – if needed, also adjust at the OS locale.
  • Takes effect on the client after a Notes client restart, on the server after a server restart.
  • Complementary to CountryLanguage, Region (locale family).
