The CDF_EPOCH_DIFF function compares two epoch (date and time) values and returns the difference in milliseconds (default) or microseconds.
Examples
CDF_EPOCH, epoch, 2005,6,1,10,18,17,2,/COMPUTE
CDF_EPOCH, epoch1, 2005,6,1,10,18,17,2,3,4,5,/COMPUTE
CDF_EPOCH, epoch2, 2005,6,1,10,18,17,2,1,4,5,/COMPUTE
CDF_EPOCH, epoch3, 2005,6,1,10,18,17,1,/COMPUTE
PRINT, 'Difference between epoch1 and epoch, in milliseconds: ',$
CDF_EPOCH_DIFF(epoch1,epoch)
PRINT, 'Difference between epoch1 and epoch, in microseconds: ',$
CDF_EPOCH_DIFF(epoch1,epoch,/MICRO_SECONDS)
PRINT, 'Difference between epoch1 and epoch2, in microseconds: ',$
CDF_EPOCH_DIFF(epoch1,epoch2,/MICRO_SECONDS)
PRINT, 'Difference between epoch1 and epoch3, in microseconds: ',$
CDF_EPOCH_DIFF(epoch1,epoch3,/MILLI_SECONDS)
Syntax
Result = CDF_EPOCH_DIFF(epoch1, epoch2 [, /MILLI_SECONDS] [, /MICRO_SECONDS])
Arguments
epoch1
epoch2
An epoch value returned from CDF_EPOCH or CDF_EPOCH16 with the COMPUTE keyword set, or from CDF_VARGET or CDF_VARGET1.
Keywords
MILLI_SECONDS
Set this keyword to return the difference in milliseconds. This is the default.
MICRO_SECONDS
Set this keyword to return the difference in microseconds.
