(which includes T-Mobile USA and Metro PCS) stores and maintains call detail records in several different native formats. The most current call detail records are stored and maintained in Coordinated Universal Time ("UTC"). UTC is not a time zone, but a time standard that is the basis for civil time and time zones worldwide. UTC operates independently of country specific time zones and/or seasonal adjustments, such as Daylight Savings Time. Older call detail records are stored and maintained in the time zone associated with the user's location at the time of the call. UTC is the equivalent of GMT. If you received call detail records in a spreadsheet format, they are timestamped in UTC. If call records have been produced, the transactions reflect UTC timestamps that correspond with the dates and times specifically identified in the legal demand. A list of the most commonly requested records is listed below, together with the associated native formats. VOICE CALLS, CELL SITES, SMS - Most recent 24 months UTC VOICE CALLS - Older than 24 months (postpaid only) User Location at time of call SMS - Older than 24 months (postpaid only) PST/PDT MMS - any age (if available) PST/PDT Data Sessions - up to 180 days UTC The resources below will assist your preparation of a description of records that corresponds with UTC.
