MS Time Zone

Denotes the MS Timezone. This is expressed in 15 minute intervals from the UTC.

time sample

Taking 0x4A00 from the sample CDR, we get (0x4A & 0x08) != 0 so it is a negative offset. 0x4A)>>4 + 10*(0x4A & 0x7 ⇒ 4 + 10*2 ⇒ 24 multiples of 15 minutes ⇒ 24/4 = 6.

For further details on this type of format, see the GSM Specifications.
