The CDF_ENCODE_TT2000 function encodes a single value or an array of CDF_TIME_TT2000 value(s) into the standard date and time character string(s), including possible leap seconds. The default format of the string is ISO 8601 format:
yyyy-mm-ddThh:mm:ss.cccuuunnn
Tip: See the CDF_LEAPSECONDS_INFO routine for up-to-date info on current leap seconds.
Examples
epoch_string = '2005-12-04T20:19:18.176321123'
epoch = CDF_PARSE_TT2000(epoch_string)
PRINT, CDF_ENCODE_TT2000(epoch)
CDF_TT2000, epoch2, 2005, 12, 4, 20, 19, 18, 176, 321, /compute
PRINT, CDF_ENCODE_TT2000(epoch2, epoch=0)
IDL Output
2005-12-04T20:19:18.176321123
04-Dec-2005 20:19:18.176321123
Syntax
Result = CDF_ENCODE_TT2000(Epoch [, EPOCH={0 | 1 | 2 | 3}] )
Return Value
