CHST-FM is a Canadian radio station, broadcasting at 102.3 FM in London, Ontario. The station uses the on-air brand and format Jack FM. Jack FM broadcasts with an average effective radiated power of 5.84 kW from the CFPL-TV tower in Southwest London. Due to CHST-FM's low ERP relative to some London area radio stations, its broadcast signal covers only Middlesex, Elgin, and Oxford counties. The station's coverage to the west is impeded by co-channel WGRT in Port Huron, Michigan.
Approved by the CRTC in 1999, CHST was launched by CHUM Limited in 2000. It originally used the brand Star 102.3 with a hot adult contemporary format, but was rebranded as the adult hits format Bob FM in July 2003.
On June 21, 2010, CTVglobemedia announced it had entered into an agreement to sell the station to Rogers Communications. The sale was approved by the CRTC on December 22, 2010. Under Rogers ownership, the station retained its variety hits format and the Bob FM branding, despite Rogers holding Canadian rights to the Jack FM brand. However, it did adopt elements of the Jack FM brand, such as a similar logo and the "Playing whatever! Whenever!" slogan.

The Chamorro Time Zone, formerly the Guam Time Zone, is a United States time zone which observes standard time ten hours ahead of Coordinated Universal Time (UTC+10:00). The clock time in this zone is based on the mean solar time of the 150th meridian east of the Greenwich Observatory.
The zone includes the U.S. territories of Guam and the Northern Mariana Islands, where the Chamorro people are the original inhabitants. Since Daylight Saving Time (DST) is not observed anywhere in this zone, the time is always known as Chamorro Standard Time (ChST).
The zone is two hours behind Wake Island Time Zone and 15 hours ahead of North American Eastern Time Zone.
Chamorro Standard Time is practically the same time as Australian Eastern Standard Time, especially in Queensland, which does not observe DST.
The Mariana Islands were not part of any time zone legislated by the U.S. Congress until the Chamorro time zone was established by Public Law 106-564 on December 23, 2000. Prior to 2000, Guam's standard time was based on territorial Public Law 5-25 (1959) which designated the time Guam Standard Time. The law (Guam Code Annotated, Title 1, Section 1010) was established long before the Northern Mariana Islands came under U.S. sovereignty in 1986, and still remains in the book today despite federal overlap.
