UTC+01:24 is an identifier for a time offset from UTC of +01:24. This time corresponding to that offset was the local mean time at the Warsaw meridian also known as Warsaw mean time.
Since the early nineteenth century, it was commonly used for timekeeping purposes in the lands of the former Polish-Lithuanian Commonwealth.
On 5 August 1915, Warsaw switched to the Central European Time, and the rest of Poland quickly followed suit.
