20 May 1916; Saturday

On Main Gate Guard from 9.15. Managed pretty well. Had a lot to do at night especially. Leishman helped me through and I put on the guard room clock at 2 o’clock1.

Daylight Saving Bill came into force at midnight2.


  1. See note below re daylight saving. “I put on the guard room clock” presumably means “I advanced the guard room clock by one hour.” 2 A.M. was the time at which the hour officially changed. 

  2. Daylight saving time was introduced in Britain by the Summer Time Act 1916 and was implemented in 1916 as GMT plus one hour and Dublin Mean Time plus one hour (Dublin time was 25 minutes behind London at this time). For 1916, DST extended from 21 May to 1 October.
